Structure of CdTe/ZnTe superlattices
The structure of CdTe/ZnTe superlattices has been analyzed through (J /28 x-ray diffraction, photoluminescence, and in situ reflection high-energy electron diffraction (RHEED) measurements. Samples are found to break away from CdxZn 1 _x Te buffer layers as a consequence of the 6% lattice mismatch in this system. However, defect densities in these superlattices are seen to drop dramatically awa...
متن کاملInterface vibrational modes and interface structure of CdSe/ZnTe superlattices
Interfacial vibrational modes ~IFM’s! of CdSe/ZnTe superlattice are shown for perfect and atomically rearranged interfaces with four probable exchange configurations. In addition to the IFM at 222 cm originating from single interface Zn-Se ‘‘wrong’’ bonds ~WB’s!, another IFM at 235 cm occurs due to atomic rearrangement at the interfaces, which is attributed to double Zn-Se WB’s. Raman scatterin...
متن کاملRole of magnesium in band gap engineering of sub-monolayer type-II ZnTe quantum dots embedded in ZnSe
Modification of the bandgap of sub-monolayer type-II ZnTe quantum dots (QDs), by means of direct incorporation of magnesium in the QDs, is reported. Nitrogen co-doped QDs embedded in a ZnSe matrix have been grown by a migration-enhanced molecular beam epitaxy technique. Incorporation of Mg in the ZnTe QDs decreases the valence band discontinuity, leading to reduced localization of the holes, wh...
متن کاملVALENCE BAND STRUCTURE OF STRAINED-LAYER Si-Si0.5Ge0.5 SUPERLATTICES
We calculate the valence subband dispersion of Sio,5Ge,,5 Si strained layer structures grown on a Si (001) substrate and on a Si0,,5Ge0,25 buffer. We use the 6x6 Luttinger-Kohn Hamiltonian, including the effects both of strain and of the split-off band. The heavy-hole zone centre states are separated by over 60meV from the light-hole states and the highest valence subband has a low zone-centre ...
متن کاملBand structure and gaps of triangular graphene superlattices.
The general properties of long wavelength triangular graphene superlattices are studied. It is shown that Dirac points with and without gaps can arise at a number of high-symmetry points of the Brillouin zone. The existence of gaps can lead to insulating behaviour at commensurate fillings. Strain and magnetic superlattices are also discussed.
