Strong quantum-confined Stark effect in germanium quantum-well structures on silicon

Article Abstract:

Thin quantum-well structures made from III-V semiconductors such as GaAs, InP and their alloys exhibit the much stronger quantum-confined Stark effect (QCSE) mechanism, which allows modular structures with only micrometers of optical path length, but these materials are difficult to integrate with silicon electronic devices. Germanium is routinely integrated with silicon in electronics but earlier silicon-germanium structures have not shown strong modulation effects.

Mesostructured germanium with cubic pore symmetry

Article Abstract:

Cubic mesostructured germanium, MSU-Ge-1, with gyroidal channels containing surfactant molecules, separated by amorphous walls that lie on thegyroid (G) minimal surface as in the mesoporous silica MCM-48 is described. A consequence of this new structure for germanium, which has walls only one nanometer thick, is a wider electronic energy bandgap than has crystalline or amorphous Ge.

Germanium takes holey orders

Article Abstract:

Detailed approaches to synthesis of periodic porous structures made of germanium and the significant advances in the structuring of germanium frameworks are presented. The optical properties of the semiconductor materials depend on their dimensions, composition and the presence of other molecules attached to their surface.
