Structural properties of Ge nanostructured films synthesized by laser ablation

Abstract: We compare the structural properties of nanostructured Ge films deposited by pulsed laser deposition (PLD) and crossed-beam pulsed laser deposition (CBPLD). We show that CBPLD is an excellent technique for reduction of micron-sized particles which affect the quality of nanostructured films. We demonstrate that CBPLD in the equivalent dynamic conditions of PLD yields similar nanostructured Ge films with particle sizes of $20 nm. Combining different characterization techniques we conclude that under these deposi… Show more

“…The diameters of the spheres increased relatively with temperature, suggesting that there is a correlation between deposition temperatures and growth in particle sizes. Similar results have been reported by Riabinina et al [4]. Fig.…”

“…The advantage of this approach consists of ultraclean conditions of synthesis [ 25 ], which enables one to avoid all undesirable toxic impurities, typical for chemical routes. Several studies demonstrated the synthesis of Ge-based (Ge, GeO 2 , GeSi) nanocrystalline films [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ] on the substrate or colloidal solutions of NPs [ 42 , 43 , 44 ] by using methods of pulsed laser ablation in gaseous or organic liquid media, respectively. Although such Ge crystallites may be of interest for optoelectronic, photovoltaic and other applications, their PL properties do not look promising for bioimaging use.…”

“…Group IV nanocrystals and porous films can be synthesized using different techniques such as sputtering, ion implantation (9), plasma enhanced chemical deposition (PECVD) (10,11) and reactive pulsed laser deposition (RPLD) (12)(13)(14)(15)(16)(17)(18)(19). These systems have been intensely investigated both from the theoretical (20)(21)(22)(23) and experimental (24)(25)(26) points of view, focusing in particular on their growth, structural characterization and luminescence properties (where applicable), with a view to understanding the relation between their structure and their optical properties.…”
