The thermal conductivity of a bundle of boron nanoribbons can be significantly higher than that of a single free-standing ribbon, and can be switched between this enhanced value and that of a single nanoribbon by wetting the interface between the nanoribbons with various solutions.

A topological insulator illuminated with circularly or linearly polarized light produces a photocurrent that depends on the helicity or polarization of the light, respectively.

A tunnel junction that consists of a ferroelectric barrier layer sandwiched between two electrodes can operate as a fast, low-power and non-volatile nanoscale solid-state memory.
