Silicon and germanium nanocrystals: properties and

Silicon and germanium NCs have revealed to be promising on the areas of optical luminescence, in which size-dependent luminescence and absorption of Si NCs is consistently reported. Memory devices are another promising area of application. So far, the greatest challenges continue to be the control of surface, interface and other deep levels, misfit strain, and doping efficiency.

Difference Between Silicon and Germanium Compare

30/09/2011· The key difference between silicon and germanium is that the Germanium has d electrons, but Silicon does not have any d electrons. Silicon and germanium, are both in the same group (group 14) of the periodic table. Hence, they have four electrons in the outer energy level. Moreover, they occur in two oxidation states, +2 and +4.

Application of electronic properties of germanium to

Abstract of EP0452741 A method of inhibiting dopant diffusion in silicon using germanium is provided. Germanium is distributed in substitutional sites in a silicon lattice to form two regions of germanium interposed between a region where dopant is to be introduced and a region from which dopant is to be excluded, the two germanium regions acting as a dopant diffusion barrier.
