Unique electronics
Quasiparticle band-gap
With a high surface area and unique electronic (quasiparticle band-gap) properties, few-layered MoSe2 nanosheets have great potential as an advanced electrode material for supercapacitors and energy storage applications. Chemically-exfoliated MoSe2 nanosheets possess an obvious NIR absorption peak, leading to effective photothermal therapy of human lung cancer.
