  • Description:

    Semiconductor quantum dots provide a platform for studying individual electron spins as they interact with a complex solid state environment. Unlike most quantum dot systems, colloidal nanocrystal quantum dots can achieve sufficient confinement to operate at room temperature, with relatively robust electron spin coherence. The strong confinement in these nanostructures leads to significant effects caused by electron-hole exchange interactions, variation in particle size and shape, and surface defects. This seminar will focus on recent progress in understanding how these considerations give rise to the observed electron spin phenomena in semiconductor nanocrystal quantum dots.
