Nanotemplated lead telluride thin films
Nanotemplated lead telluride thin films
Direct lyotropic liquid crystalline templating has been successfully applied to produce nanostructured
IV–VI semiconductor PbTe thin films by electrodeposition both on gold and n-type (100) silicon substrates.
The PbTe films were characterized by transmission electron microscopy, X-ray diffraction and
polarized optical microscopy and the results show that the films have a regular hexagonal nanoarchitecture
with a high crystalline rock salt structure and exhibit strong birefringence. The optical absorption
measurements using Fourier transform infrared spectroscopy show that the nanostructured PbTe films
have a direct band gap of 0.37 eV.

Abstract
Direct lyotropic liquid crystalline templating has been successfully applied to produce nanostructured
IV–VI semiconductor PbTe thin films by electrodeposition both on gold and n-type (100) silicon substrates.
The PbTe films were characterized by transmission electron microscopy, X-ray diffraction and
polarized optical microscopy and the results show that the films have a regular hexagonal nanoarchitecture
with a high crystalline rock salt structure and exhibit strong birefringence. The optical absorption
measurements using Fourier transform infrared spectroscopy show that the nanostructured PbTe films
have a direct band gap of 0.37 eV.
