HgTe/HgCdTe quantum wells with the inverted band structure have been probed using far infrared
magneto-spectroscopy. Realistic calculations of Landau level diagrams have been performed to
identify t...

In this work we demonstrate that the device presented by Koo et al. [Science 325, 1515 (2009)]
in InAs quantum wells has indeed realized the Datta-Das spin-injected field effect transistor. The oscil...

We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...
