Ab initio study of lattice dynamics of group IV semiconductors using pseudohybrid functionals for extended Hubbard interactions
Wooil Yang, Seung-Hoon Jhi, Sang-Hoon Lee +1
We study the lattice dynamics of group IV semiconductors using fully ab-initio extended Hubbard functional. The onsite and intersite Hubbard interactions are determined self-consis…
First-Principles Study of Two-Dimensional Ferroelectrics Using Self-Consistent Hubbard Parameters
Jiawei Huang, Sang-Hoon Lee, Andrew Supka +2
The discovery of two-dimensional (2D) materials possessing switchable spontaneous polarization with atomic thickness opens up exciting opportunities to realize ultrathin, high-dens…
Efficient First-Principles Approach with a Pseudohybrid Density Functional for Extended Hubbard Interactions
Sang-Hoon Lee, Young-Woo Son
For fast and accurate calculations of band gaps of solids, we present an {\it ab initio} method that extends the density functional theory plus on-site Hubbard interaction (DFT+…
Crossover critical behavior of Ga1-xMnxAs
Sh. U. Yuldashev, Kh. T. Igamberdiev, Y. H. Kwon +5
The critical behavior of Ga1-xMnxAs in a close vicinity of the Curie temperature was experimentally studied by using the thermal diffusivity measurements. Taking into account that…
Distribution of magnetic domain pinning fields in GaMnAs ferromagnetic films
Jungtaek Kim, D. Y. Shin, Sanghoon Lee +2
Using the angular dependence of the planar Hall effect in GaMnAs ferromagnetic films, we were able to determine the distribution of magnetic domain pinning fields in this material.…
