Abstract

Abstract

Materials with designed architectures are rapidly emerging as an exciting class of materials with adaptive and multifunctional properties. In this talk, I will present our work on fabrication of origami and kirigami architectures of atomically-thin materials, and introduce advanced, reconfigurable electronic applications.

Abstract

Abstract

Halide perovskites are intensively studied for the next generation solar cells, while their intrinsic properties, such as strong absorption, tunable bandgap, and large carrier motilities, make them ideal candidates for photodetectors. I will present the progress in developing low cost, fast photodetectors.

WC4.3 - PHOTOSWITCHING DIELECTRIC PROPERTIES USING PLASMONIC CORE-SHELL HYBRID OF 3D C60-CONFORMERS AT GHZ FREQUENCY

Abstract

Abstract

3D-configurated stereoisomers cis-cup-tris[C60>(DPAF-C9)] were found to exhibit photoswitchable dielectric amplification phenomena at GHz frequency. Observation was correlated to photoactivation with plasmonic energy to enhance intramolecular e-transfer. Accumulated plasmonic resonance energy was effective to distribute negative charges along the outer C60> fullerosome shell layer of trilayered NPs.

WC4.4 - ON THE CHARACTERIZATION AND MODELING OF THE CURRENT CHARACTERISTICS OF ORGANIC PHOTODIODES

Abstract

Abstract

A photodiode’s current temporal dynamics cannot be ignored to accurately characterize and rationalize its properties. We demonstrate that when the steady-state current is properly measured, an equivalent circuit model quantitatively describes the current characteristics of organic photodiodes in the dark and under illumination.
