OverviewAI-generated summary
Pargam Vashishtha is a Postdoctoral Research Fellow at the University of Arkansas at Fayetteville. His research focuses on the development and characterization of self-powered photodetectors, particularly those utilizing heterostructures of materials like molybdenum disulfide (MoS₂) and gallium nitride (GaN). These devices are designed for broadband spectral response, covering ultraviolet (UVC) to near-infrared (NIR) regions, and exhibit high-temperature reliability.
His recent publications detail the fabrication of GaN nano-towers for self-powered UV photodetectors, and the creation of MoS₂/GaN thin film heterostructures for bidirectional photodetectors with an extended active spectrum. Vashishtha has also investigated MoS₂/Sb₂Se₃ heterostructures for self-powered broadband photodetection and Sb₂Se₃-based photodetectors for high-performance broadband applications. Further work includes thermally resilient, nano-fenced MoS₂-based photodetectors for NIR optical signals and GaN-based pyramidal self-powered UV photodetectors for use in rugged environments.
With a highly cited designation, Vashishtha has authored 88 publications with 1,888 citations, and holds an h-index of 26. His work is marked by recent activity, with publications extending into 2024 and a potential publication in 2025.
