Abstract: | A wide variety of materials can be isolated into large-area, thin sheets. These new structural elements range from graphene and transition metal dichalcogenides, i.e., true 2D materials, to inorganic nanomembranes (NMs), including single-crystal semiconductor sheets as thin as several nanometers. Single-crystal materials in sheet form provide a platform for fascinating new science and numerous technology breakthroughs. The key enablers of this platform are thinness (compliancy/ flexibility, novel mechanical properties, ready strain management), a large surface-area-to-volume ratio, and, in semiconductors, the ability to manipulate electronic/optoelectronic properties. I will describe efforts that build on this progress to provide opportunity for new science and for improved materials that may enable better performance in device structures of dizzying diversity. In the first category are quantitative modelling of electrical transport through nanosheets, growth on freestanding nanosheets, and a new approach to achieve THz radiation based on solid-state cyclotron sources. In the category of improved materials are stable passivation of Ge by graphene, advanced neural interfaces, and strain-engineered of MoS2 nanosheets to obtain optical energy funnels. | |
