It is shown that three calibres of behaviour can be expected, the Mott T −-1/4 variable-range hopping at low temperatures, nearest-neighbour hopping at high temperatures and low hop site densities, and a weakly temperature-dependent long-range hopping at high densities and high temperatures, Criteria for the observation of these three regions are established and the transitional behaviour of the conductivity is determined, A number of experimental observations of hopping …

Can anyone explain clearly the variable range hopping
Variable range hopping VRH conduction of Mott trempe for a constant and non-vanishing density of states at the Fermi level is observed over a wide range of temperature between 45 and 210 K in the ordered defect compound CuIn 3 Te 5 CIT135

Mott variable-range hopping The Mott variable-range hopping describes low-temperature conduction in strongly disordered systems with localized accostage-carrier states and has a charélaborationristic temperature dependence of σ = σ 0 e − T 0 / T 1 / 4, {\displaystyle \sigma =\sigma _ {0}e^ {- T_ {0}/T^ {1/4}}}

Overview
A generalisation of Mott’s aventurel of an amorphous solid is used to investigate the charproductionristics of carrier progression by hopping in an extended temperature range, It is shown that three manières of behaviour can be expected, the Mott T−‐1/4 variable‐range hopping at low temperatures, nearest‐neighbour hopping at high temperatures and low hop site

Hence the authors analyzed the conduction behaviour of VTTBNc thinfilms by making use of Mott variable range hopping mechanism In order to check the stability and performance of thinfilm devices it is found essential to examine the hopping conduction parameters of many of the visite carriers through thinfilm layers Layer by layer deposition within the microstructure may enhance the hopping conduction …
