Nettet30. des. 2024 · There are other semiconductor materials like GaAs with other ratios (Mobility electrons ≤8500 cm2 V-1s-1 ; Mobility holes ≤400 cm2 V-1s-1). There are also semiconductors with hole mobility higher than electron mobility e.g. PbS or PbTe. In general, the mobility has to be calculated using the Matthiessen rule: 1 / μ = ∑ i 1 / μ i. NettetIt can be shown that Eq. (2.1) is true for both electrons and holes. 1 The kinetic energy in Eq. (2.1) may be used to estimate the thermal velocity, vth, of electrons and holes by equating the energy with or.
