Abstract_John A ROGERS "SEMICONDUCTOR NANOMATERIALS AND 3D MICROSYSTEMS"
ABSTRACT
Complex, three dimensional (3D) assemblies of micro/nanomaterials form naturally in biological systems, where they provide sophisticated function in even the most basic forms of life. In spite of their broad potential utility in man-made devices, design options for analogous abiotic 3D mesostructures are severely constrained by the comparatively primitive capabilities that are available with established techniques for materials growth, assembly and 3D printing. This talk summarizes progress on (1) semiconductor nanomaterials and designs for microscale LEDs, biosensors and active electronic components, and (2) strategies that rely on geometric transformation of preformed 2D interconnected collections of these elements into 3D mesoscale architectures by controlled processes of compressive buckling. The emphasis is on the foundational materials and mechanics principles, computational approaches that enable inverse designs, and applications in areas ranging from bio-inspired microfliers as platforms for environmental sensing to open microfluidic/electronic networks as functional interfaces to 3D cell cultures, including spheroids and assembloids formed from them.
