Abstract
In the present work, firstly, a first-principles study of the structural, electronic, and electron transport properties of the HgxMg1−xTe (HMT) ternary compound is performed using the ABINIT package and the results are compared with Cd0.9Zn0.1Te (CZT) as a current room-temperature photodetector. Next, the response functions of Hg0.6Mg0.4Te and Cd0.9Zn0.1Te under electromagnetic irradiation with 0.05 MeV, 0.2 MeV, 0.661 MeV and 1.33 MeV energies are simulated by using the MCNP code. According to these simulations, the Hg0.6Mg0.4Te ternary compound is suggested as a good semiconductor photodetector for use at room temperature.
