Development of the Ge-MDST instrument structure with an induced p-type channel

The conditions for the growth of n-type Ge conduction layers by the HW CVD method with the parameters required to create a Ge-TIR transistor with an induced p-type channel are determined. The conditions of deposition by electron beam deposition and subsequent annealing of layers of a high-k dielectric ZrO2:Y2O3 are optimized, allowing to achieve a leakage current of 5 × 10–6 A/cm2. For the developed instrument structure, some parameters of the Ge-TIR transistor were calculated, such as the channel length, the maximum voltage between the drain and the source, and the breakdown voltage.
