Abstract: H58.00005 : Advances in Computing Charge Transport and Hot Carrier Dynamics from First Principles*
4:54 PM–5:30 PM
1) Accurate calculations of the carrier mobility in polar semiconductors and oxides, where we show new methods to treat complex materials with structural phase transitions (e.g., perovskites) and provide insight into charge transport in organic molecular crystals with tens of atoms in the unit cell.
2) The ultrafast dynamics and detailed scattering mechanisms of excited (so-called “hot”) carriers. We will discuss a new parallel algorithm to propagate in time the electron BTE, and efforts to extend it to the coupled electron and phonon dynamics. The application of this framework will focus on hot carriers in gallium nitride light emission technologies.
Code development efforts, open problems and future directions will be outlined.
