Zusammenfassung

A two-dimensional semimetal is discovered in the (013) HgTe quantum well with a thickness of d = 14 nm, which is much smaller than those previously studied. It is found that such semimetal is characterized by the same band overlap as the wells with d =18-22 nm having the same orientation, but here the impurity scattering of both electrons and holes is much more pronounced. The electron cyclotron ...
