Brightening interlayer excitons by electric-field-driven hole transfer in bilayer WSe2
Tianyi Ouyang, Erfu Liu, Soonyoung Cha +8
We observe the interlayer A1s^I, A2s^I, and B1s^I excitons in bilayer WSe2 under applied electric fields using reflectance contrast spectroscopy. Remarkably, these interlayer excit…

Semi-empirical Pseudopotential Method for Monolayer Transition Metal Dichalcogenides
Raj Kumar Paudel, Chung-Yuan Ren, Yia-Chung Chang
We present a semi-empirical pseudopotential method for accurately computing the band structures and bloch states of monolayer transition metal dichalcogenides(TMDCs), including MoS…

Efficient Band Structure Calculation for Transitional-Metal Dichalcogenides Using the Semiempirical Pseudopotential Method
Raj Kumar Paudel, Chung-Yuan Ren, Yia-Chung Chang
The Semiempirical Pseudopotential Method (SEPM) has emerged as a valuable tool for accurately determining band structures, especially in the realm of low-dimensional materials. SEP…
