STM Exploration of Binary Nanocrystals

ORAL

Abstract

Multi-component nanocrystals provide an exciting platform for creating flexibly tailored electronic nanodevices due to their ``built-in'' heterojunction interface. Such systems are potentially useful for creating inexpensive energy-conversion devices from abundant materials. Using scanning tunneling microscopy and spectroscopy, we have investigated the structural and electronic properties of binary CdS/Cu2S nanorods bound to a metal surface. We will present spectroscopic results that provide new insight into energy level alignment within these dual-phase nanocrystals.
