Abstract:

A study of the pressure response of single crystalline Fe1mxSi1+x samples revealed beyond an initial increase a pressure driven reduction of the band gap Eg . Concomitantly, there is a well resolvable change of the variable range hopping conductivity, presumably caused by an increase of the characteristic temperature of the system due to band broadening effects in the electronic density of states.
