Spectroscopic studies of atomic defects and bandgap renormalization in semiconducting monolayer transition metal dichalcogenides
Tae Young Jeong, Hakseong Kim, Sang-Jun Choi +5
Assessing atomic defect states and their ramifications on the electronic properties of two dimensional van der Waals semiconducting transition metal dichalcogenides (SC TMDs) is th…
Stability and dopability of native defects and group-V and -VII impurities in single-layer MoS2
Ji-Young Noh, Minkyu Park, Yong-Sung Kim +1
We investigate the native defects, the Mo substitutional impurities of the group-VB and -VIIB elements, and the S substitutional impurities of the group-VA and -VIIA elements in si…
Instability of Amorphous Oxide Semiconductors via Carrier-Mediated Structural Transition between Disorder and Peroxide State
Ho-Hyun Nahm, Yong-Sung Kim, Dae Hwan Kim
The excited holes occupying the valence band tail states in amorphous oxide semiconductors are found to induce formation of meta-stable O peroxide defects. The valence ban…
Rich variety of defects in ZnO via an attractive interaction between O-vacancies and Zn-interstitials
Yong-Sung Kim, C. H. Park
As the concentration of intrinsic defects becomes sufficiently high in O-deficient ZnO, interactions between defects lead to a significant reduction in their formation energies. We…
