Strain-Engineered Photoelectrodes | ||
Our DFT calculations show that strain induced during heteroepitaxial growth can alter the anion order in thin-films of the oxynitride LaTiO2N, large compressive strain leading to a trans order and spontaneous polarization. Strained thin films of this solar light absorber will thus suppress exciton recombination due to the internal dipolar field.
