The structural and electronic properties of the in-plane hybrids consisting of siligene (SiGe), and its derivatives in both mono and bilayer forms are investigated within density functional theory. Among several pristine and hydrogenated configurations, the so-called chair conformation is energetically favorable for monolayers.

WebOct 1, 2024 · The electrical properties of a SiGe alloy channel from Si to Ge, for electron and hole mobilities are investigated. Although SiGe NMOS shows degraded electron mobility until 85% because of alloy scattering, abrupt mobility improvement with the high composition SiGe channel is observed because of a band structure modification. WebThe band structure of SiGe has been calculated using the coherent-potential approximation in conjunction with a realistic but local pseudopotential model. The effects of alloy disorder manifest themselves in complex band energies, each with an imaginary part inversely …
WebThe band structure gives a map of the only states allowed in a material. When an electron reaches the edge of the band structure, it must jump to another band, because the energy of a photon causes an "excitation" of the electron. The band structure is similar to a map of all the different quantum states in a material, where the electrons have ... WebAug 30, 2024 · Given the pseudo-direct nature of the lonsdaleite SiGe band gap, the measured optical properties – in particular the high radiative recombination rate – of SiGe are surprising. To begin to understand this unusual behaviour, we have undertaken first principles calculations of the electronic structure evolution of lonsdaleite SiGe alloys.
