Dependence of carrier mobility on nanocrystal size and ligand length in PbSe nanocrystal solids.
We measure the room-temperature electron and hole field-effect mobilities (micro(FE)) of a series of alkanedithiol-treated PbSe nanocrystal (NC) films as a function of NC size and the length of the alkane chain. We find that carrier mobilities decrease exponentially with increasing ligand length according to the scaling parameter beta = 1.08-1.10 A(-1), as expected for hopping transport in gran...
متن کاملHole Mobility in Nanocrystal Solids as a Function of Constituent Nanocrystal Size.
Solids of semiconductor nanocrystals (NCs) are semiconductors in which the band gap can be controlled by changing the size of the constituent NCs. To date, nontrivial dependencies of the carrier mobility on the NC size have been reported. We use the time-of-flight (TOF) technique to measure the carrier mobility as a function of the NC size and find that the hole mobility of the NC solid increas...
متن کاملNanocrystal targeting in vivo.
Inorganic nanostructures that interface with biological systems have recently attracted widespread interest in biology and medicine. Nanoparticles are thought to have potential as novel intravascular probes for both diagnostic (e.g., imaging) and therapeutic purposes (e.g., drug delivery). Critical issues for successful nanoparticle delivery include the ability to target specific tissues and ce...

متن کاملNanocrystal Quantum Dots
214 Semiconductor lasers are ubiquitous in modern society and play a key role in technologies ranging from CD players to optical telecommunications. Current-generation lasers have high power output and low lasing thresholds, are stable over a wide range of temperatures, and are cheap and easy to produce. Still, there is room for improvement. We are developing a new type of laser based on ultras...
