Observation of spin-splitting crossing between subbands in the optically detected cyclotron-resonance spectra ofIn0.53Ga

Effects of band offset and nonparabolicity on the effective mass of two-dimensional electron gases in modulation-δ-dopedGa0.47InDai1, Chen2, Lo3 1997Phys. Rev. BSelf Cite6031View full textAdd to dashboardCite

“…Even though several reports have been devoted to the study of this problem, the effective mass including nonparabolic correction is always less than the experimental result. [7][8][9][10][11] It has been pointed out that this discrepancy can be attributed to the effect of the wave-function penetration into the barrier; 9,11 however, there is still no clear evidence to demonstrate the penetration effect. In this paper we present direct measurements of the in-plane effective mass of the two-subband occupied electron gas in modulation-␦-doped Ga 1Ϫx In x As-based heterostructures with a very large difference of conduction-band offset by using far-infrared ͑FIR͒ optically detected cyclotron resonance ͑ODCR͒.…”
