Recent progresses in the fundamental knowledge of low-dimensional systems and nanomaterials have opened up enormous possibilities for diverse applications. In this context, the development of a broad range of atomically thin, layered materials have become an exciting new direction of research for a large community of physicists, chemists, materials scientists, electrical and mechanical engineers alike. The meteoric rise of graphene as a 2D functional material for a range of applications has paved the way for the ├ó┬?┬?discovery├ó┬?┬Ł of a wide variety of other 2D, atomically thin, and layered materials with a broad range of electronic and optical properties. In this talk, the author will present some of our recent results in photonics, optoelectronics and nanomechanics using some of these atomically thin materials, focusing on the theme of structural and functional tunability of these materials. Specifically, author will discuss how graphene can be used to design tunable photo detectors and ultrafast actuators with extremely high performances. Further, the author will talk about how quantum size-effects can be used to widely tune the optical properties of bismuth selenide, and present an array of exciting new results from atomically thin molybdenum disulfide. Finally, author will introduce the idea of 2D alloys - materials with tunable compositions in a purely 2D lattice. These materials and systems are just a small representative of the new field of 2D materials that can potentially revolutionize materials science in the next decade.
