At sufficiently high pressures, wurtzite structure zinc oxide (WZnO)
can be transformed to the cubic rocksalt (R-ZnO)
structure. The R-ZnO exhibits semiconductor behavior with an
indirect wide band gap of Eg ¼ 5:5 eV. ...
The development of sensitive, selective, stable and suitable gas sensors for
monitoring toxic gases in mineshafts and the environment in general, requires the
basic understanding of the active sensing material. This ...
