摘要
Cyclotron resonance (CR) experiments have been performed to study the two-dimensional gas in InAs-AlSb-GaSb structures in tilted magnetic fields. The CR spectra exhibit characteristic behavior associated with the crossover from the 2D to the 3D nature of electron motion. New spectroscopic effects, such as the appearance of additional lines in CR spectra and their strong dependence on electron density and tilt angle, have been observed. The tilted-field CR technique allows us to probe the band bending of InAs quantum wells.
