Abstract
Great strides have been made in the understanding of electronic and optical properties of semiconducting single-walled carbon nanotubes (SWCNTs) in the past two decades. With optical transitions at near-infrared wavelengths, and diameter- and chirality-tunable electronic structures, SWCNTs are promising candidates for near-infrared nanolasers. In this talk, I will discuss our recent exploration of stimulated emission from SWCNTs by coupling them to whispering gallery modes supported by polymer microspheres through a self-assembly process.In contrast to the many exciting developments in the excitonic frontier, electron spins, which are ubiquitous in solid state materials and highly relevant to spintronic and quantum information science, in SWCNTs are relatively less understood. In this talk, I will also discuss our recent study of electron spins in SWCNTs.
