THz detectors with HgTe and InSb quantum wells

Terahertz-frequencies in semiconductor quantum wells are of interest due to the opportunity for making devices that operate at THz frequencies. In this study we present magnetotransport and magnetooptical data obtained in the magnetic field range 0 <; B <; 7T at QH detectors patterned as Corbino rings on AlInSb/InSb/AlInSb and HgCdTe/HgTe/HgCdTe quantum well wafers.
