Magnetospectroscopy of Zn-doped InP to 30 T

While the III-V alloy InP finds increasing applications in high-power and high-speed electronics, optical fiber communications, and radiation detection, the knowledge of its impurity states, especially in magnetic fields, remains sparse. Fig. 1 summarizes present knowledge of the Zn acceptor states in InP in zero and applied field. The unperturbed energies of acceptor states have been calculated by Baldereschi and Lipari. (1-3) The ground-state energy has recently been calculated by Wang and Chen. 4 Energies of the Zn acceptor have been determined experimentally by Kubota et al.(5) using photoluminescence (PL) and by Wenzel et al.(6) using electronic Raman scattering (ERS). Magnetospectroscopy(7,8) has previously been conducted to 17.5 T; the present work extends this to 30 T.
