Defying Diamagnetism: Anomalous Redshift and Robust Chiral Spin Mixing in 2D Perovskites under High Magnetic Fields up to 50 T
D. Y. Park, S. Park, Yongmin Kim +4
We report circularly polarized magneto-photoluminescence (MPL) measurements on the enantiomeric pair of two-dimensional chiral perovskites R- and S-(C4H9NH3)2PbI4 in pulsed magneti…
Temperature Dependence of the Optical Transition Characteristics of MAPbClBr Single Crystals
D. Y. Park, Y. H. Shin, Yongmin Kim
Methylammonium-lead-halide compounds have emerged as promising bandgap engineering materials due to their ability to fine-tune the energy gap through halogen element mixing. We pre…
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…
Temperature dependence of the Stark shifts of Er transitions in ErO thin film on Si (001)
Halim Choi, Y. H. Shin, Yongmin Kim
Optical transitions of an ErO film on a Si substrate grown by using a metal-organic chemical vapor deposition technique were investigated in a wide temperature (300 K $\sim…
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…
Specific heat study of Ga1-xMnxAs
Sh. U. Yuldashev, Kh. T. Igamberdiev, Sejoon Lee +5
Specific heat measurements were used to study the magnetic phase transition in Ga1-xMnxAs. Two different types of Ga1-xMnxAs samples have been investigated. The sample with a Mn co…
