Transition Metal Dichalcogenides for High−Performance Aqueous Zinc Ion Batteries

Hierarchically Nanostructured Transition Metal Oxides for Lithium‐Ion Batteries

Lithium-ion batteries (LIBs) have been widely used in the field of portable electric devices because of their high energy density and long cycling life. To further improve the performance of LIBs, it is of great importance to develop new electrode materials. Various transition metal oxides (TMOs) have been extensively investigated as electrode materials for LIBs. According to the reaction mecha...

Nanostructured Transition Metal Chalcogenides as Materials in Lithium Ion Batteries

Exciton formation in monolayer transition metal dichalcogenides.

Two-dimensional transition metal dichalcogenides provide a unique platform to study excitons in confined structures. Recently, several important aspects of excitons in these materials have been investigated in detail. However, the formation process of excitons from free carriers has yet to be understood. Here we report time-resolved measurements on the exciton formation process in monolayer sam...

Patterning Superatom Dopants on Transition Metal Dichalcogenides.

This study describes a new and simple approach to dope two-dimensional transition metal dichalcogenides (TMDCs) using the superatom Co6Se8(PEt3)6 as the electron dopant. Semiconducting TMDCs are wired into field-effect transistor devices and then immersed into a solution of these superatoms. The degree of doping is determined by the concentration of the superatoms in solution and by the length ...
