Abstract

In this talk, we review recent applications of chemical doping in organic molecular and polymer semiconductors. We begin with a motivation for doping these materials in device applications, and with a review of doping mechanisms in molecular solids. We then provide an overview of the reducing or oxidizing power of a number of n- and p-type molecular dopants, respectively, and their effect on the electronic structure and conductivity of both vacuum- and solution-processed...

Abstract

Development of nanotechnology and low-power electronics is leading to the transformative self-powered nanosystems that exhibit ultra-small size, supersensitivity, extraordinary multi-functionality and extremely low power consumption. One of the grand challenges for the next generation nanosystem is the controlled growth of functional nanomaterials and the development of the nanoscale energy harvester to power the system. Zinc oxide (ZnO) is a piezoelectric and semiconduc...
