Article Synopsis
  • The study uses Rode's iterative method to analyze the semi-classical transport properties of n-type AlGaAs, focusing on scattering mechanisms like ionized impurity and polar optical phonon (POP).
  • It identifies two crystal structures: tetragonal and body-centered tetragonal, with the latter exhibiting higher electron mobility, making it preferable for high mobility applications.
  • At room temperature, inelastic POP scattering is the primary contributor to electron mobility, revealing that Rode's method provides a more accurate estimate compared to the relaxation time approximation.

To realize a graphene based spintronic device, the prime challenge is to control the electronic structure of edges. In this work we find the origin of the spin filtering property in edge boron doped zigzag graphene nanoribbons (ZGNRs) and provide a guide to preparing a graphene based next-generation spin filter based device. Here, we unveil the role of orbitals (p-electron) to tune the electronic, magnetic and transport properties of edge B doped ZGNRs.

The hexagonal boron nitride (h-BN) is traditionally considered to be inert. In sharp contrast to the inert behavior of free-standing hexagonal boron nitride (h-BN), we propose the catalytic property of h-BN monolayer on Ni(111) substrate using first-principles density functional theory investigation. The interaction of O2 molecule with the h-BN/Ni(111) substrate results in nondissociative adsorption of the molecule along with elongation of the O-O bond.
