Abstract
Capacitance-Voltage (C-V) and Conductance-Voltage (C-V) study of Hg0.53Cd0.47Te/CdTe interface is reported. The conductance peak at the onset of strong inversion for n-type Hg0.53CdTe0.47 MIS structure has been ascribed to indirect tunneling assisted by interface states. For p-type Hg0.53Cd0.47Te MIS structure, the oscillatory conductance in strong inversion region is caused by bulk trap assisted tunneling from 3D valence band to 2D subband of the inversion surface. This shows that tunneling for p-type MIS structure is insensitive to the interface states. From the generation-recombination conductance peaks in depletion region for p-type Hg0.53Cd0.47Te, conductance method is used to obtain the density, response time and capture cross-section of CdTe/HgCdTe interface states and their distributions in energy band gap.
