Ultrafast photocurrent and absorption microscopy of few-layer TMD devices isolate rate-limiting dynamics driving fast and efficient photoresponse
Kyle T. Vogt, Su-Fei Shi, Feng Wang +1
Despite inherently poor interlayer conductivity, photodetectors made from few-layer devices of 2D transition metal dichalcogenides (TMDs) such as WSe and MoS can still yiel…
An Environmentally Stable and Lead-Free Chalcogenide Perovskite
Tushar Gupta, Debjit Ghoshal, Anthony Yoshimura +14
Organic-inorganic halide perovskites are intrinsically unstable when exposed to moisture and/or light. Additionally, the presence of lead in many perovskites raises toxicity concer…
Catalyst-Free And Morphology-Controlled Growth Of 2D Perovskite Nanowires for Polarized Light Detection
Debjit Ghoshal, Tianmeng Wang, Hsin-Zon Tsai +2
Two-dimensional (2D) perovskites or Ruddleson Popper (RP) perovskites have emerged as a class of material inheriting the superior optoelectronic properties of two different materia…
Communicating Two States in Perovskite Revealed by Time-Resolved Photoluminescence Spectroscopy
Yanwen Chen, Tianmeng Wang, Zhipeng Li +5
Organic-inorganic perovskite as a promising candidate for solar energy harvesting has attracted immense interest for its low-cost preparation and extremely high quantum efficiency.…
