The field of nanophotonics is based on the ability to confine light to sub-diffractional dimensions. In the infrared, this requires compression of the wavelength to length scales well below that of the free-space values…

Polar semiconductors can support phonon polaritons, collective excitations comprising coherent oscillation incoming light and atomic motion of the material, in direct analogy to plasmon polaritons in metals…

As electronic devices continue to reduce towards nanoscale dimensions, understanding heat transport mechanisms at these scales becomes vital…

Despite recent advances in the field of nanochemistry, very little is known about the interactions of organic precursors used in the synthesis…
