Magnetic properties of HgTe quantum wells

Using analytical formulas as well as a finite-difference scheme, we investigate themagnetic field dependence of the energy spectra and magnetic edge states of HgTe/CdTe-based quantum wells in the presence of perpendicular magnetic fields and hard walls for the band-structure parameters corresponding to the normal and inverted regimes. Whereas one can not find counterpropagating, spin-polarized ...

Energy of the conduction band in near critical point fluids

The study of the evolution of the conduction band in dense gases and supercritical fluids near the critical point has been complicated by a lack of precise experimental measurements. Both photoemission from an electrode immersed in the fluid and field ionization of a molecule doped into the fluid have been used to probe solvent density effects on the energy of an excess electron as a function o...

Quantum spin hall insulator state in HgTe quantum wells.

Recent theory predicted that the quantum spin Hall effect, a fundamentally new quantum state of matter that exists at zero external magnetic field, may be realized in HgTe/(Hg,Cd)Te quantum wells. We fabricated such sample structures with low density and high mobility in which we could tune, through an external gate voltage, the carrier conduction from n-type to p-type, passing through an insul...

Edge States in p-n Junctions in Inverted Band HgTe Quantum Wells

We investigate current noise of lateral p-n junctions, electrostatically defined in 14 nm–wide HgTe-based quantum wells (QWs) with inverted band structure. Consistent with previous experiments on 8-10 nm QWs, the p-n junctions resistances are close to h/2e, indicating the edge states contribution to transport. Taking into account contacts heating, we find that the observed shot noise is suppres...

THE CONDUCTION BAND SPIN SPLITTING IN TYPE-I STRAINED A N D UNSTRAINED (Galn)As/InP QUANTUM WELLS

-We present the first successful optically detected magnetic resonance experiments (ODMR) on strained and unstrained Ga~In~ _,As/InP type-I quantum wells. The resonances attributed to electrons are in general anisotropic and detailed results are given for the composition range 0.4 < x < 0.6. Extrapolating to the binary end points, i.e. lnAs and GaAs close agreement with existing results is foun...
