    • Abstract


      Absorption spectra of hexagonally structured, tellurium excess p-type cadmium telluride (CdTe) grown from vapour phase having conductivity $2.529\times 10^{4}$ ($\Omega$ cm)$^{-1}$ was studied in the range 700–880 nm. The existence of phononassistedindirect transition was confirmed. The direct and indirect bandgaps and the involved phonon energy were identified. The analysis revealed a band tailing and the presence of a strong internal electric field responsible for the tunnelling of charge carriers.
