A solar thermal fuel can include a plurality of photoswitchable moieties associated with a nanomaterial. The plurality of photoswitchable moieties can be densely arranged on the nanomaterial, such that adjacent photoswitchable moieties interact with one another. The solar thermal fuel can provide high volumetric energy density.

Ferroelectric semiconductor devices are provided by including a ferroelectric layer in the device that is made of a material that is not ferroelectric in bulk. Such layers can be disposed at interfaces to promote ferroelectric switching in a semiconductor device. Switching of conduction in the semiconductor is effected by the polarization of a mechanically bi-stable material. This material is not ferroelectric in bulk but can be considered to be when the thickness is sufficiently reduced down to a few atomic layers. Devices including such ferroelectric layers are suitable for various applications, such as transistors and memory cells (both volatile and non-volatile).
