Highly Efficient Perovskite Nanocrystal Light‐Emitting Diodes Enabled by a Universal Crosslinking Method

Advances in Materials, 2016
The preparation of highly efficient perovskite nanocrystal light-emitting diodes is shown. A new trimethylaluminum vapor-based crosslinking method to render the nanocrystal films insoluble is applied. The resulting near-complete nanocrystal film coverage,

Size-dependent bandgap and particle size distribution of colloidal semiconductor nanocrystals [PDF]

, 2017
A new analytical expression for the size-dependent bandgap of colloidal semiconductor nanocrystals is proposed within the framework of the finite-depth square-well effective mass approximation in order to provide a quantitative description of the quantum

Optoelectronic sensitization of carbon nanotubes by CdTe nanocrystals [PDF]

, 2009
We investigate the photoconductance of single-walled carbon nanotube-nanocrystal hybrids. The nanocrystals are bound to the nanotubes via molecular recognition.

High Throughput 512Mbps True Random Number Generation Using Uncertainty in Mobile Communication Bands

IEEE Access
This study presents a new approach to generating true random numbers by exploiting the random nature inherent in mobile communication networks. Taking advantage of fluctuations in total users, user activity rate, and channel fading, we receive a raw ...

Theoretical study of solid iron nanocrystal movement inside a carbon nanotube

, 2013
We use a first-principles based kinetic Monte Carlo simulation to study the movement of a solid iron nanocrystal inside a carbon nanotube driven by the electrical current. The origin of the iron nanocrystal movement is the electromigration force.
