Scalable Cyclic Olefin Copolymer Encapsulation for High Optical Quality of TMD Monolayers
Suprova Das, Md Tarik Hossain, Zlata Fedorova +8
Monolayer transition metal dichalcogenides (TMDs) combine a direct bandgap, strongly bound excitons, and pronounced second-order optical nonlinearity, which makes them promising ma…
Interface Symmetry and Electrostatic Stabilization of Strain-Resilient Janus Heterobilayers for Flexible Piezotronics
Surender Kumar, Mostafa Torkashvand, Stefan Velja +1
The electronic structure of conventional two-dimensional transition metal dichalcogenides (TMDs) is highly sensitive to lattice deformation, often leading to indirect-to-direct ban…
Electronic localization and optical activity of strain-engineered transition-metal dichalcogenide nanobubbles
Stefan Velja, Alexander Steinhoff, Jannis Krumland +2
Strain-engineered transition-metal dichalcogenide nanobubbles are promising platforms for quantum emission, as revealed by recent experimental observations. In this work, we presen…
Atomistic Origin of Photoluminescence Quenching in Colloidal MoS2 and WS2 Nanoplatelets
Surender Kumar, Markus Fröhlich, Stefan Velja +8
Large chemical tunability and strong light-matter interactions make colloidal transition metal dichalcogenide (TMD) nanostructures particularly suitable for light-emitting applicat…
Edge Magnetism in Colloidal MoS2 Triangular Nanoflakes
Surender Kumar, Stefan Velja, Muhammad Sufyan Ramzan +1
The control of localized magnetic domains at the nanoscale holds great promise for next-generation spintronic applications. Colloidal transition metal dichalcogenides nanostructure…
