摘要: Abstract Equations are derived for the absorption constant of Pb 1− x Sn Te (LTT) and Hg Cd ,Te (HCT) including Burstein-Moss shift edge. The equations given in terms k−p band structure parameters appropriate to two alloy systems. Comparison calculated spectra with experimental values reported date indicate satisfactory agreement. Some new approximate relations calculating Fermi level n -type HCT either degenerate or classical carrier concentration regime.
