Confined polar optical phonons in semiconductor double heterostructures: an improved continuum approach
F. Comas, I. Camps, N. Studart +1
Confined polar optical phonons are studied in a semiconductor double heterostructure (SDH) by means of a generalization of a theory developed some years ago and based on a continuo…
Electron-phonon interaction in quantum-dot/quantum-well semiconductor heterostructures
F. Comas, Nelson Studart
Polar optical phonons are studied in the framework of the dielectric continuum approach for a prototypical quantum-dot/quantum-well (QD/QW) heterostructure, including the derivatio…
Interface optical phonons in spheroidal dots: Raman selection rules
F. Comas, C. Trallero-Giner, Nelson Studart +1
The contribution of interface phonons to the first order Raman scattering in nanocrystals with non spherical geometry is analyzed. Interface optical phonons in the spheroidal geome…
High field transport in strained Si/GeSi double heterostructure: a Fokker-Planck approach
F. Comas, Nelson Studart
We report calculations of high electric field transport for the case of a strained Si/GeSi double heterostructure (DHS) considering transport along the Si channel and by applying t…
High-field transport properties of bulk Si: A test for the Fokker-Planck approach
F. Comas, Nelson Studart
High electric-field transport parameters are calculated using an analytical Fokker-Planck approach (FPA), where transport is modeled as a drift-diffusion process in energy space. W…
