Cyclotron resonance using microwave and far infrared radiation is used to study nonparabolicity of electron effective masses and spin splitting effects in high mobility CdTe, ZnTe and ZnSe. Mobilities close to 1×106 cm2/Vs are found but only for hig

The current status and future perspectives of cyclotron resonance (CR) experiments in SiC are given, with a brief review of published results. CR experiments have so far been successful only in 3C, 4H and 6H SiC. Among them 3C has the best establishe

Intersubband transitions in ${\mathrm{In}}_{\mathrm{x}}$${\mathrm{Ga}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$As/InP quantum wells have been studied by magnetic circular dichroism (MCD) of the absorption. The g values of the heavy and light holes in th

Optically detected spin resonance was used to measure the effective g-value of electrons at the conduction band minimum in type-I quantum wells. The experiments showed that the spin resonance is induced by electric dipole transitions, and hence is no

The current knowledge on extrinsic and intrinsic point defects in CdTe and Cd 1− x Zn x Te as obtained by electron paramagnetic resonance and related techniques is reviewed. Special attention will be paid to the properties of intrinsic defects such

Vanadium doped CdTe is studied by electron paramagnetic resonance (EPR), photo-EPR, and optical absorption. The EPR measurements identify vanadium substitutional for Cd in the oxidation states V 2+ and V 3+ . Whereas V 3+ shows the well-known isotrop

We studied ZnSe single quantum wells with well widths from 4 to 1 nm by optically detected cyclotron resonance (ODCR). In the samples grown by metal organic vapour phase epitaxy, where the residual shallow donor concentration is still of the order of
