Thus surface-(S)-to-volume (V) ratio (S/V) = 3/r for such nanoparticle dramatically increases as its size is reduced Since surface atoms have different environment in contrast to interior atoms, their behaviors to any external excitation are completely different. The size effect becomes ...
Nanoelectronics require semiconductor nanomaterials with high electron mobility like Ge nanolayers. Phonon and electron states in nanolayers undergo size-dependent changes induced by confinement and surface effects. Confined electrons an... V Poborchii,J Groenen,PI Geshev,... - 《Nanoscale》 被引量: ...
Exploiting the light-driven crosslinking process, different colour CdSe-based core-shell quantum dots can be photo-patterned; quantum dot patterns of red, green and blue primary colours with a sub-pixel size of 4 μm × 16 μm, corresponding to a resolution of >1400 pixels per ...

Asymmetric Janus transition metal dichalcogenide MoSSe is a promising catalytic material due to the intrinsic in-plane dipole of its opposite faces. The atomic description of the structures observed by experimental techniques is relevant to tuning and op
