Combination of Optical Transitions of Polarons with Rashba Effect in Methylammonium Lead Tri-halide Perovskites under High Magnetic Fields
Halim Choi, Yong Ho Shin, Chang Soo Park +6
We investigate photoluminescence (PL) transitions of MAPbX (X = I, Br and Cl) organic-inorganic hybrid perovskite single crystals under magnetic fields of up to 60 T. In thes…

Deuterium permeation in ErO thin film fabricated on a type 316L stainless steel substrate
Halim Choi, Y. H. Shin, Yongmin Kim
A metal-oxide film can be used as a hydrogen-isotope permeation barrier in the fuel circulation system for nuclear fusion. We fabricated ErO thin film on a type 316L stainl…
