Query: Semi-classical electronic transport properties of ternary compound
  AlGaAs$_2$: Role of different scattering mechanisms   We present a comprehensive investigation of semi-classical transport
properties of n-type ternary compound AlGaAs2, using Rode's iterative method.
Four scattering mechanisms, have been included in our transport calculation,
namely, ionized impurity, piezoelectric, acoustic deformation and polar optical
phonon (POP). The scattering rates have been calculated in terms of ab-initio
parameters. We consider AlGaAs2 to have two distinct crystal geometries, one in
tetragonal phase (space group: ), while the other one having body centered
tetragonal crystal structure (space group:). We have observed higher electron
mobility in the body centered tetragonal phase, thereby making it more suitable
for high mobility device application, over the tetragonal phase. In order to
understand the differences in electron moblities for these two phases,
curvatures of the E-k graph of the conduction bands for these phases have been
compared. At room temperature, the dominant contribution in electron mobility
was found to be provided by inelastic POP scattering. We have also noted that
mobility is underestimated in relaxation time approximation as compared with
the Rode's iterative approach.
