摘要
Indium is a p-type dopant that can be considered for p-channel germanium metal oxide semiconductor field effect transistors. As such understanding its diffusion properties over a range of temperatures and pressures is technologically important. This can be realized in the cBa"broken vertical bar model in which the defect Gibbs energy is proportional to the isothermal bulk modulus (B) and the mean volume per atom (a"broken vertical bar). In the present study elastic and expansivity data is used in the framework of the cBa"broken vertical bar model to derive the indium diffusion coefficient in germanium in the temperature range 827-1,176 K. The calculated results are in excellent agreement with the available experimental data.
