Electron relaxation and mobility in the inverted band quantum well CdTe/Hg₁₋xCdxTe/CdTe

Electron relaxation processes at nitrogen temperatures in CdTe/Hg₁₋xCdxTe/CdTe quantum well (QW) with an inverted band structure is modelled. In this
 structure, scattering by longitudinal optical phonons, charged impurities, acoustic phonons
 and interfaces were taken into account....

Description
Summary:Electron relaxation processes at nitrogen temperatures in CdTe/Hg₁₋xCdxTe/CdTe quantum well (QW) with an inverted band structure is modelled. In this
 structure, scattering by longitudinal optical phonons, charged impurities, acoustic phonons
 and interfaces were taken into account. It was found that for undoped and lightly doped
 QWs (concentration of background n-type charged impurities in the well is 10¹⁴ – 10¹⁶ cm-³
 or less), for x close to the band inversion value 0.16, the electron mobility grows
 considerably when the QW width decreases. This mobility is higher for samples with
 smaller concentrations of charged impurities.
