Time Domain Spectroscopy of Graphene
… structure can be quantified. I will explain how screened exchange and electron phonon self energies provide corrections to the band structure for different times after carrier excitation. Lastly, I will describe measurements that determine the extent of electron-electron correlations in graphene …

Band Engineering of Advanced Materials for Semiconductor Devices
… approximation (GGA) and the state-of-the-art screened exchange (sX) functional. Calculations using the sX functional accurately reproduce the experimental band gap values, whereas GGA is more effective in describing the optical properties. The advanced sX method and the more efficient GGA + U …

Density Functional Simulations of Defect Behavior in Oxides for Applications in MOSFET and Resistive Memory
Defects in the functional oxides play an important role in electronic devices like metal oxide semiconductor field effect transistors (MOSFETs) and resistive random-access memories (ReRAMs). The continuous scaling of CMOS has brought the Si MOSFET to its physical technology limit and the …
