Аннотация
© Published under licence by IOP Publishing Ltd. Electron transport in single delta-Si doped pseudomorphic quantum wells with increasing donor concentration analyzed in a temperature range 2-300K. Hall effect and Shubnikov-de Haas oscillations studied at low temperatures. Temperature dependences of electron sheet concentration differ: samples with higher doping show significant increase of electron consentration at high temperature, while for the lightly doped it has a minor temperature sensitivity due to the band peculiarities of donor ionization. Electron mobility increases and then decreases at higher electron concentration, although the second quantum well subband remains unpopulated.
