| Abstract | The influence of addition of Zn on band parameters of ZnxCdyHg1-x-yTe solid solution at different temperatures (4.2-200 K) was investigated. The cyclotron resonance at 4.2 K and magnetophonon resonance at 77-200 K were used to determine band structure parameters. The temperature dependence of band structure parameters (energy gap, effective mass of electron) for the composition of series of epilayers (x varied in 0.08-0.20 range and y — 0.07-0.12) was obtained. It is found that band structure parameters for some compositions (for example x = 0.17, y = 0.08) are almost independent from temperature and equal: γL1= 19.55, γL2=38.5, KL = 6.48, F = -0.5, Eg = 0.35 eV, Ep = 17.9 eV. The effective mass of electrons was found to be greater with addition of Zn while the effective mass of heavy holes is left unchanged. PACS numbers: 71.25.Tn |
