Non-equilibrium materials by fs-laser texturing and hyperdoping of silicon

Ultrafast-laser hyperdoped semiconductors have begun to be utilized for optoelectronic applications, but there is a need to better understand their fundamental physical properties. In this presentation, we discuss recent work on the basic science of ultrafast-laser structuring, time-resolved melting, resolidification, and hyperdoping, and the optical and electronic properties hyperdoped silicon. These aspects of ultrafast-laser hyperdoped semiconductors are central to hyperdoped materials science and device design.
