摘要

Zn1-xMnxTe and Cd1-xMnxTe crystals doped with phosphorus have been investigated by means of the measurement of Hall effect, photoluminescence and reflectance. By annealing under high pressure of nitrogen (up to 4 MPa) at T = 800 degreesC for a week, a free hole density as high as 5 x 10(18) cm(-3) was achieved in Zn0.95Mn0.05Te, while in Cd0.99Mn0.01Te it was only 8 x 10(18) cm(-3). The phosphorus acceptor binding energy in Zn0.975Mn0.025Te and Cd0.99Mn0.01Te was found to be (0.036 +/- 0.002) eV and (0.054 +/- 0.002) eV, respectively. [References: 6]
