The unexpected beneficial effect of the L-valley population on the electron mobility of GaAs nanowires
- Departamento de Electrónica, Universidad de Granada, Av. Fuentenueva S/N, 18071, Granada (Spain)
The impact of the L-valley population on the transport properties of GaAs cylindrical nanowires (NWs) is analyzed by numerically calculating the electron mobility under the momentum relaxation time approximation. In spite of its low contribution to the electron mobility (even for high electron populations in small NWs), it is demonstrated to have a beneficial effect, since it significantly favours the Γ-valley mobility by screening the higher Γ-valley energy subbands.
