SI SIGE HETEROSTRUCTURES FOR NANO ELECTRONIC DEVICES

Si/Ge embedded alloyed nanocrystals, we have shown thedependence of the absorption spectra on the alloying andthe presence of a different localization for HOMO andLUMO. Regarding the SiGe nanowires, we demonstratedthat those which show a clear interface between Si and Geo[r]

For this analysis, if we control the variation of voltage changes Udk from value of -Um to +Um we could obtain the changing in firing angle α from 0 to π. Fig. 4. Simulation circuit (measure the waveform in pulse generator controlled by the sample). The circuit consists of two chanels[r]

The electrodes are generally treated as electron reservoirs and semi-infinite bulkstructures. To model and simulate such an open system, DFT must be extended.1.4 OverviewThis thesis will focus on the development of a simulation method based on abinitio density functional theory (DFT) combined with n[r]

Si/SiGe QC structure. In other words, the intersubbandtransitions in the QC structures rely on the interwellcoupling in the QWs. This is because the wave func-tions in the QC structures are no longer confined to asingle well, but penetrate into barriers and extend overthe entire region[r]
