Fermi-Level Tuning of G-Doped Layers.

Recently, geometry-induced quantum effects were observed in periodic nanostructures. Nanograting (NG) geometry significantly affects the electronic, magnetic, and optical properties of semiconductor layers. Silicon NG layers exhibit geometry-induced doping.

Large enhancement of the thermoelectric figure of merit in a ridged quantum well.

Recently, new quantum features have been observed and studied in the area of ridged quantum wells (RQWs). Periodic ridges on the surface of the quantum well layer impose additional boundary conditions on the electron wavefunction and reduce the quantum state density. As a result, the chemical potential of RQWs increases and becomes ridge-height-dependent.
