A particularly interesting property of this mesostructured cubic Ge framework is the substantial blue-shift in optical absorption at 1.42 eV relative to 0.66 eV of bulk Ge. This large blue-shift can be understood by considering the change in the density of the electronic energy states caused by the substantial dimensional reduction of the Ge structure from the bulk Ge (infinity wall thickness) to an 1 nm. Similar large blue-shifted band gaps by 0.76 eV are also observed in Ge nanocrystals of 4 nm in diameter, which is a consequence of quantum confinement effects [42], Whether...

The first experimental realization of intersubband lasers without inversion exploited the nonparabolicity of the conduction subbands and local population inversion near k=0 even though the lowest subband may have larger global occupation [25]. Later on, valence-band-based designs have been proposed [26-28], Intervalence band emitters based on Si-Ge structures have been...

Apart from the defect structures and Til, the structures we have mentioned are all essentially of the 6 6 coordination type. In the SnS (GeS) structure the distortion of the octahedral coordination groups is such as to bring three of the six original neighbours much closer than the other three, so that the structure could alternatively be described as consisting of very buckled 6-gon nets in which...
