P-doped bilayer graphene based photodetector with colloidal quantum dots absorber

Photodetector based on chemical free p-type doped graphene conduction channel and core-shell CdSe/ZnS type I quantum dots absorber was studied. Chanel conductivity modulation of 20% was observed under illumination. Responsivity of 0.72 A/W with 19ms response time and 1.4*10 8 Jones specific detectiv...

Summary:Photodetector based on chemical free p-type doped graphene conduction channel and core-shell CdSe/ZnS type I quantum dots absorber was studied. Chanel conductivity modulation of 20% was observed under illumination. Responsivity of 0.72 A/W with 19ms response time and 1.4*10 8 Jones specific detectivity were achieved.
