Second harmonic generation in SiC polytypes
Sergey N. Rashkeev, Walter R. L. Lambrecht, Benjamin Segall
LMTO calculations are presented for the frequency dependent second harmonic generation (SHG) in the polytypes 2H, 4H, 6H, 15R and 3C of SiC. All independent tensor components are c…
Total energy differences between SiC polytypes revisited
Sukit Limpijumnong, Walter R. L. Lambrecht
The total energy differences between various SiC polytypes (3C, 6H, 4H, 2H, 15R and 9R) were calculated using the full-potential linear muffin-tin orbital method using the Perdew-W…
Efficient ab-initio method for the calculation of frequency dependent non-linear optical response in semiconductors: application to second harmonic generation
Sergey N. Rashkeev, Walter R. L. Lambrecht, Benjamin Segall
A LMTO implementation of Aversa and Sipe's length-gauge formalism for calculating the full frequency dependent second-harmonic generation in the independent particle approximation…
