One-dimensional warm electron transport in GaN quantum well wires at low temperatures
One-dimensional warm electron coefficient (β) and Ohmic mobility μ₀ in a square quantum well wire of GaN are studied for lattice temperatures in the range of 4-10 K, which are important from the application point of view. Electron scattering via deformation potential acoustic, piezoelectric, and ion...

One-dimensional warm electron coefficient (β) and Ohmic mobility μ₀ in a square quantum well wire of GaN are studied for lattice temperatures in the range of 4-10 K, which are important from the application point of view. Electron scattering via deformation potential acoustic, piezoelectric, and ionized impurity are incorporated in the calculations. Carrier distribution is considered to be a heated Fermi-Dirac. Ohmic mobility (μ₀) is larger for a quantum well wires of greater width and decreases slowly with the rise of lattice temperature. β is negative, and its magnitude falls with increasing lattice temperature and is greater for wider width of the wire.
