Chemical States and Local Structure in Cu-Deficient CuInSe2 Thin Films: Insights into Engineering and Bandgap Narrowing
Ahmed Yousef Mohamed, Byoung Gun Han, Hyeonseo Jang +6
The Cu-deficient CuxInSe2 (x larger than 0.3) phase can be stabilized as a thin film. A uniform Cu-deficient composition with a chalcopyrite structure was obtained by the precision…
Atomic and Electronic Structures of Correlated SrRuO3/SrTiO3 Superlattices
Seung Gyo Jeong, Ahmed Yousef Mohamed, Deok-Yong Cho +1
Atomic-scale precision epitaxy of perovskite oxide superlattices provides unique opportunities for controlling the correlated electronic structures, activating effective control kn…
Direct evidence of electronic interaction at the atomic-layer-deposited MoS2 monolayer/SiO2 interface
Minji Lee, Yejin Kim, Ahmed Yousef Mohamed +5
The electronic structure of an atomic-layer-deposited MoS2 monolayer on SiO2 was investigated using X-ray absorption spectroscopy (XAS) and synchrotron X-ray photoelectron spectros…
Self-Assembling Oxide Catalyst for Electrochemical Water Splitting
Daniel S. Bick, Andreas Kindsmueller, Deok-Yong Cho +8
Renewable energy conversion and storage, and greenhouse gas emission-free technologies are within the primary tasks and challenges for the society. Hydrogen fuel, produced by alkal…
Influence of oxygen vacancy on the electronic structure of HfO film
Deok-Yong Cho, Jae-Min Lee, S. -J. Oh +4
We investigated the unoccupied part of the electronic structure of the oxygen-deficient hafnium oxide (HfO) using soft x-ray absorption spectroscopy at O and Hf $N_…
