Co/AlP/Co, Co/GaN/Co as magnetic tunnel junctions
Gokaran Shukla, Stefano Sanvito, Geunsik Lee
AlP and GaN are wide band-gap semiconductors (SC) uses in opto-electronic industry as light emitting diodes. Here we investigate it as future perspective candidate for insulating b…
Tip-induced nano-engineering of strain, bandgap, and exciton dynamics in 2D semiconductors
Yeonjeong Koo, Yongchul Kim, Soo Ho Choi +8
The tunability of the bandgap, absorption and emission energies, photoluminescence (PL) quantum yield, exciton transport, and energy transfer in transition metal dichalcogenide (TM…
Unified low-energy effective Hamiltonian and the band topology of -block square-net layer derivatives
S. I. Hyun, Inho Lee, Geunsik Lee +1
In recent years, low-dimensional materials with tetragonal (orthorhombic ) space group having square-net (chain-like) substructure of -block elements have been st…
La-Doped BaSnO Electron Transport Layer for Perovskite Solar Cells
Chang Woo Myung, Geunsik Lee, Kwang S. Kim
Due to the photo-instability and hysteresis of TiO electron transport layer (ETL) in perovskite solar cells (PSCs), novel electron transport materials are highly demanded. Here…
Rashba-Dresselhaus Effect in Inorganic/Organic Lead Iodide Perovskite Interfaces
Chang Woo Myung, Saqib Javaid, Kwang S. Kim +1
Despite the imperative importance in solar-cell efficiency, the intriguing phenomena at the interface between perovskite solar-cell and adjacent carrier transfer layers are hardly…
A New Perspective on the Role of A-site Cation in Perovskite Solar Cells
Chang Woo Myung, Jeonghun Yun, Geunsik Lee +1
As the race towards higher efficiency for inorganic/organic hybrid perovskite solar cells (PSCs) is becoming highly competitive, a design scheme to maximize carrier transport towar…
