This article describes an inkjet printed, biocompatible, heterostructure photodetector that was constructed using inks of photo-active molybdenum disulfide (MoS2) and electrically conducting graphene which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration, which is a condition where the photosensitive retinal tissue degrades with aging, eventually compromising vision. The absence of effective therapeutic remedies for patients with this disorder has motivated the development of such devices to restore some degree of visual function.

Article on the characterization of noise in a flux qubit using macroscopic resonant tunneling between the two lowest lying states of a bistable rf SQUID. Analysis of these results indicates that the dominant source of low energy flux noise in this device is a quantum mechanical environment in thermal equilibrium.
