Abstract

The great decrease of electron mobility with increasing sheet electron concentration ns in modulation-doped AlGaAs/GaAs/AlGaAs quantum wells is observed. This effect is explained by increasing scattering of degenerated electrons by polar optical phonons. At ns >10 15 m -2 , the mobility decrease exceeds the increase of ns, and the channel conductivity decreases with increasing ns.
