One of the great challenges in the semiconductor and electronics industries is that as nanoscale features get smaller and processes get faster, enormous amounts of heat need to be quickly carried away from the nanostructures. The Kapteyn/Murnane group has made the counter-intuitive discovery that it is easier to cool these nanostructures when they are arranged closely together. The researchers...

When research associate Wei Xiong and graduate student Dan Hickstein studied quantum dots by shining laser light on them in the gas phase, they got some surprising results. The tiny chunks of material responded differently to series of two laser pulses — depending on their size. Scientists already knew that most of their quantum dots would end up with at least part of an electron wandering...

The transfer of heat in nanostructures works differently than it does in the large objects we see and use in everyday life. In nanostructures, both classical and quantum mechanical effects are important. In solids, for example, phonons carry heat energy away from its source as they scatter and diffuse through a material. However, when the heat source is very tiny (with nanoscale dimensions),...
