“…The mass analyzer is a vital part of any ion soft landing instrument as it enables mass‐selection of the ions of interest from the full distribution of ions produced by the source, forming a purified ion beam comprised of a single type of atomic or molecular ion in a specific charge state. Mass analyzers used for ion soft landing include the linear quadrupole (Judai et al, ; Bottcher et al, ; Gologan et al, ; Alvarez et al, ; Deng et al, ), linear ion trap (Watanabe et al, ; Ouyang et al, ; Gregor et al, ), magnetic sector (Mayer et al, ; Kemper et al, ), Wien filter (Franchetti et al, ; Luo et al, ), variations of time‐of‐flight (TOF) (von Issendorff & Palmer, ), and hybrid instruments which combine multiple mass analyzers in a tandem configuration (Miller et al, ; Geiger et al, ; Rauschenbach et al, ). In addition, ion mobility spectrometry has been used recently to separate ions prior to deposition based on their drift times (Davila et al, ; Hoffmann & Verbeck, ).…”

“…Soft‐ and reactive landing of mass‐selected ions onto surfaces has become a subject of substantial interest due to its potential as a method for the highly‐controlled preparation of materials for a variety of practical applications and fundamental investigations in chemistry, physics, and materials science (Grill et al, ; Gologan et al, , ; Laskin et al, ; Wang et al, ; Johnson et al, ; Cyriac et al, ; Verbeck et al, ). Recent studies have suggested future applications of ion soft landing in the separation of proteins and conformational enrichment of peptides (Gologan et al, ; Wang & Laskin, ), production of peptide and protein microarrays for high‐throughput biological screening (Ouyang et al, ; Blake et al, 2004b; Volny et al, ), preparation of thin films for use in composite materials (Saf et al, ; Rauschenbach et al, ), characterization of redox‐active proteins (Pepi et al, ), chiral enrichment of organic compounds (Nanita et al, ), processing of graphene (Rader et al, ), deposition of carbon clusters (Loffler et al, ), and preparation of model catalysts through deposition of ionic clusters, nanoparticles, and organometallics (Judai et al, ; Vajda et al, ; Kaden et al, ).…”

Soft‐ and reactive landing of mass‐selected ions is gaining attention as a promising approach for the precisely‐controlled preparation of materials on surfaces that are not amenable to deposition using conventional methods. A broad range of ionization sources and mass filters are available that make ion soft‐landing a versatile tool for surface modification using beams of hyperthermal (<100 eV) ions. The ability to select the mass‐to‐charge ratio of the ion, its kinetic energy and charge state, along with precise control of the size, shape, and position of the ion beam on the deposition target distinguishes ion soft landing from other surface modification techniques. Soft‐ and reactive landing have been used to prepare interfaces for practical applications as well as precisely‐defined model surfaces for fundamental investigations in chemistry, physics, and materials science. For instance, soft‐ and reactive landing have been applied to study the surface chemistry of ions isolated in the gas‐phase, prepare arrays of proteins for high‐throughput biological screening, produce novel carbon‐based and polymer materials, enrich the secondary structure of peptides and the chirality of organic molecules, immobilize electrochemically‐active proteins and organometallics on electrodes, create thin films of complex molecules, and immobilize catalytically active organometallics as well as ligated metal clusters. In addition, soft landing has enabled investigation of the size‐dependent behavior of bare metal clusters in the critical subnanometer size regime where chemical and physical properties do not scale predictably with size. The morphology, aggregation, and immobilization of larger bare metal nanoparticles, which are directly relevant to the design of catalysts as well as improved memory and electronic devices, have also been studied using ion soft landing. This review article begins in section 1 with a brief introduction to the existing applications of ion soft‐ and reactive landing. Section 2 provides an overview of the ionization sources and mass filters that have been used to date for soft landing of mass‐selected ions. A discussion of the competing processes that occur during ion deposition as well as the types of ions and surfaces that have been investigated follows in section 3. Section 4 discusses the physical phenomena that occur during and after ion soft landing, including retention and reduction of ionic charge along with factors that impact the efficiency of ion deposition. The influence of soft landing on the secondary structure and biological activity of complex ions is addressed in section 5. Lastly, an overview of the structure and mobility as well as the catalytic, optical, magnetic, and redox properties of bare ionic clusters and nanoparticles deposited onto surfaces is presented in section 6. © 2015 Wiley Periodicals, Inc.

Аналіза літературних даних показує, що вивчення поверхнево нанесе-них металевих наноструктур є актуальною проблемою фізики поверхні. Кінцева структура тонких плівок залежить від значної кількости пара-метрів і чинників, таких як відмінності постійних ґратниць і коефіціє-нтів термічного розширення речовини, що наноситься, та підложжя, що, в свою чергу, приводить до виникнення внутрішніх напружень і подальшої де´радації плівки. В процесі формування моно-та багатоша-рових структур вагоме місце займають такі параметри, як температура та структура підложжя, швидкість осадження, фраґментація наноклас-терів, характеристика змочування, час нанесення, віддаль від кювети до зразку, тиск у камері та температура розтопу в кюветі. Цілеспрямо-ване керування цими параметрами уможливлює прогнозувати та ство-рювати поверхневі структури з необхідним набором фізико-хемічних властивостей.Analysis of the literature data shows that the study of surface-deposited metallic nanostructures is an actual problem of surface physics. The final structure of thin films depends on a large number of parameters and factors such as the differences between the unit-cells' sizes as well as between the coefficients of a thermal expansion of a deposited substance and substrate that leads to internal stresses and a subsequent degradation of film. Many parameters such as temperature and a substrate structure, a deposition rate, fragmentation of nanoclusters, wetting parameters, time of application, dish-sample distance, pressure in a chamber, and temperature of melt in a dish can play an important role during the mono-and multilayer structures' formation. The goal-directed control of these parameters allows prediction and fabrication of surface structures with a required set of the physical and chemical properties.

“…Complex molecules that are difficult to synthesize in solution chemistry are often used in such cases. Metal-benzene and metal-salen [salen refers to N,Nethylenebis(salicylideneaminato)] are common organometallic compounds used in soft-landing experiments (139,140). Nakajima and colleagues (139) produced V(benzene) + and V n (benzene) n+1 ions (known as multidecker sandwich cluster ions) by laser evaporation, followed by soft landing onto an argon matrix prepared on polycrystalline gold surfaces at 18 K. Subsequent IR surface analysis revealed the nondissociative deposition of the desired ions on the surface.…”

Ion/surface collisions in the ultralow-to low-energy (1-100-eV) window represent an excellent technique for investigation of the properties of condensed molecular solids at low temperatures. For example, this technique has revealed the unique physical and chemical processes that occur on the surface of ice, versus the liquid and vapor phases of water. Such instrumentdependent research, which is usually performed with spectroscopy and mass spectrometry, has led to new directions in studies of molecular materials. In this review, we discuss some interesting results and highlight recent developments in the area. We hope that access to the study of molecular solids with extreme surface specificity, as described here, will encourage investigators to explore new areas of research, some of which are outlined in this review.
