Moiré and beyond in transition metal dichalcogenide twisted bilayers
Kha Tran, Junho Choi, Akshay Singh
Fabricating van der Waals (vdW) bilayer heterostructures (BL-HS) by stacking the same or different two-dimensional (2D) layers, offers a unique physical system with rich electronic…
Twist Angle Dependent Interlayer Exciton Lifetimes in van der Waals Heterostructures
Junho Choi, Matthias Florian, Alexander Steinhoff +15
In van der Waals (vdW) heterostructures formed by stacking two monolayers of transition metal dichalcogenides, multiple exciton resonances with highly tunable properties are formed…
Growth kinetics and atomistic mechanisms of native oxidation of ZrSSe and MoS crystals
Seong Soon Jo, Akshay Singh, Liqiu Yang +14
A thorough understanding of native oxides is essential for designing semiconductor devices. Here we report a study of the rate and mechanisms of spontaneous oxidation of bulk singl…
Direct Optical-Structure Correlation in Atomically Thin Dichalcogenides and Heterostructures
Akshay Singh, Hae Yeon Lee, Silvija Gradecak
Atomically thin transition metal dichalcogenides (TMDs) have distinct opto-electronic properties including enhanced luminescence and high on-off current ratios, which can be furthe…
Near-infrared optical properties and proposed phase-change usefulness of transition metal disulfides
Akshay Singh, Yifei Li, Balint Fodor +6
The development of photonic integrated circuits would benefit from a wider selection of materials that can strongly-control near-infrared (NIR) light. Transition metal dichalcogeni…
Moiré Excitons in Van der Waals Heterostructures
Kha Tran, Galan Moody, Fengcheng Wu +19
In van der Waals (vdW) heterostructures formed by stacking two monolayer semiconductors, lattice mismatch or rotational misalignment introduces an in-plane moiré superlattice. Whil…
