The Mott variable-range hopping describes low-temperature conduction in strongly disordered systems with localized charge-carrier states and has a characteristic temperature dependence of $${\displaystyle \sigma =\sigma _{0}e^{-(T_{0}/T)^{1/4}}}$$ for three-dimensional conductance … Meer weergeven Variable-range hopping is a model used to describe carrier transport in a disordered semiconductor or in amorphous solid by hopping in an extended temperature range. It has a characteristic temperature dependence of Meer weergeven • Physics portal • Mobility edge Meer weergeven The Efros–Shklovskii (ES) variable-range hopping is a conduction model which accounts for the Coulomb gap, a small jump in the density of states near the Fermi level due to interactions between localized electrons. It was named after Alexei L. Efros Meer weergeven Webtransport could be governed by incoherent hole hopping between spatially adjacent energy states in the impurity band formed by the Mn+ implantation.15 The expected current …
Web31 aug. 2024 · The present results demonstrate that electrical conduction in both AgSbSe 2 and (AgSbSe 2) 0.9 (PbTe) 0.1 is due to hopping transport. Using experimental data and calculations, we have evaluated the temperature range of hopping conduction: 105–230 K in AgSbSe 2 and 118–220 K in (AgSbSe 2) 0.9 (PbTe) 0.1. REFERENCES Webet al.23 In this model, conduction is supposed to result from tunneling between small conducting grains separated by an insulating barrier. Such a model seems reasonable to …
