Doping semiconductor nanocrystals
Nature, 2005Doping--the intentional introduction of impurities into a material--is fundamental to controlling the properties of bulk semiconductors. This has stimulated similar efforts to dope semiconductor nanocrystals. Despite some successes, many of these efforts have failed, for reasons that remain unclear. For example, Mn can be incorporated into nanocrystals

Spectroscopy of single nanocrystals
Chemical Society Reviews, 2014As colloidal semiconductor nanocrystals are developed for a wider range of diverse applications, it becomes more important to gain a deeper understanding of their properties in order to direct synthetic efforts. While most synthetic developments are guided by changes in ensemble properties, certain applications such as those in nano-electronics and ...

Nano Letters, 2005
We have constructed and operated a nanoscale linear motor powered by a single metal nanocrystal ram sandwiched between mechanical lever arms. Low-level electrical voltages applied to the carbon nanotube lever arms cause the nanocrystal to grow or shrink in a controlled manner.

Theory Of Silicon Nanocrystals
2003The intense luminescence observed for porous silicon [1] has raised extremely interesting problems related to the possibility of using silicon in optoelectronics. One likely explanation is quantum confinement, induced by the formation of nanocrystallites.

Chemical Approaches to Semiconductor Nanocrystals and Nanocrystal Materials
1999At present “nanotechnology” is a vision rather than a reality. We do not have practical, manufacturable methods to make complex materials, machines, and electrical circuits on the 1–100 nm scale. However, there is a flourishing “nanoscience” research effort involving ideas and methods drawn from chemistry, physics, and engineering science. “Nanoscience”
