Direct growth of high-performance, scalable, and reliable electronic materials on glass is difficult owing to low thermal budget. Researchers at the Pennsylvania State University have addressed the issue by relatively low-temperature (<600 °C) metal–organic chemical vapor deposition growth of atomically thin MoS2 on multicomponent glass and fabrication of low-power phototransistors using atomic layer deposition (ALD)-grown, high-k, and ultra-thin Al2O3 as the top-gate dielectric, circumventing the challenges associated with the ALD nucleation of oxides on inert basal planes of van der Waals materials. The MoS2 photodetectors demonstrate the ability to detect low-intensity visible light at high speed and low energy expenditure of ∼100 pico Joules. The integration of photodetectors with Gorilla glass could lead to the commercial development of glass equipped with automatic sensing properties. Smart glass has a number of applications ranging from imaging to advanced robotics….read more. TECHNICAL ARTICLE
