Optical Excitations and Interactions in Metal and Semiconductor Nanostructures

Marc Achermann, University of Massachusetts Amherst

Advances in producing nanoscale materials have resulted in a wealth of novel nanomaterials with unprecedented optical and electronic properties. I will give an overview of our recent work on semiconductor, metal, and hybrid semiconductor-metal nanostructures. Using time-resolved optical spectroscopy we demonstrate that nanoscale engineering allows us to modify and control basic interactions that affect carrier and energy relaxation and transfer processes. Such processes are of fundamental importance in many photonic materials and electro-optical devices including optical sensors and light emitting and photovoltaic devices.
