“…These properties suggest the possibility of using silicon for efficient optoelectronic conversion with potential applications in photonics,5, 11 medicine,2, 12, 13 and photovoltaics (PVs) 14–17. A range of synthesis techniques have been devised18–25 and have contributed to clarify many aspects of these promising nanoscale structures. However, there is still limited control over the synthetic capabilities and in particular methods for engineering the surface characteristics are required.…”

Surface engineering of silicon nanocrystals directly in water or ethanol by atmospheric‐pressure dc microplasma is reported. In both liquids, microplasma processing stabilizes the optoelectronic properties of silicon nanocrystals. The microplasma treatment induces non‐equilibrium liquid chemistry that passivates the silicon nanocrystals surface with oxygen‐/organic‐based terminations. In particular, the microplasma treatment in ethanol drastically enhances the silicon nanocrystals photoluminescence intensity and causes a clear red‐shift (≈80 nm) of the photoluminescence maximum. The photoluminescence properties are stable after several days of storage in either ethanol or water. The surface chemistry induced by the microplasma treatment is analyzed and discussed.

“…[7][8][9] In particular, the results produced by solar cells that are based on SiNCs are scientifically important and with a very promising technological impact. [10][11][12][13][14][15] Improvements in our processing capabilities and understanding of the SiNCs behavior in photovoltaic devices may lead to the exploitation of multiexciton generation which would represent a truly new type high-efficiency solar cell. 14 The surface characteristics of SiNCs that are achievable today need however greater improvements as both the degree of passivation and the type of terminations is not satisfactory to assess and exploit the real potential of SiNC-based devices which has also fueled an interesting debate on multiexciton generation in nanocrystals in general.…”

We report on an atmospheric-pressure dc microplasma that can be used to passivate silicon nanocrystals (SiNCs) in ethanol and that stabilizes their optoelectronic properties. We show that microplasma processing enhances the SiNCs photoluminescence intensity by factor of more than ten times and ∼80 nm redshift of its maximum. The microplasma induces the replacement of hydrogen terminations with hydroxyl-/organic-based bonds. The resulting surface characteristics are responsible for the formation of conductive and stable SiNCs self-organized assemblies extending over 0.5 mm after dewetting on a substrate.

“…The relevant examples of such applications with quantitative analyses can be found in these reports [28,33,34,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68]. Anyway, we are basically done listing the complete and self-consistent definitions, propositions and proofs needed for the ionization energy theory to be considered technically "correct".…”

Logical construction of the ionization energy theory and the origin of physical categories

Logical proofs and definitions are developed to establish (1) that the energy-level spacings,for each chemical element (from the periodic table of chemical elements) can be converted to the ionization energies, (2) both and the ionization energies are unique, and (3) the averaged ionization energy of any quantum matter is proportional to the averaged ionization energy of its constituent chemical elements, if and only if 6= 0 and is not an irrelevant constant. Physical atoms are then constructed to define the physical sets such that these sets are members of a specific physical class where each class belongs to a specific physical category, P. However, there is not a single structure-preserving functor from one energy-level spacing physical category, P to another P′. Therefore, the existence of many P implies the existence of different categories of physical systems and quantum matter.
