Aligned carbon nanotube arrays have random characteristics, such as chirality and position, perpendicular to the growth direction and identical characteristics along the growth direction. We proposed and realized twin physically unclonable functions based on CNTs for secure communication.

A simple wafer-level micro-assembly technique based on light-triggered change in both surface topography and interfacial adhesion of a soft photo-sensitive polymer is developed, which allows the assembly of diverse materials and functional devices, with the printing size up to 4-inch.

Peering into the mechanics of nanosheet device structures using x-ray diffraction uniquely reveals the interplay of distinct deformation modes as dictated by their geometry.

We report a dual-band backhaul prototype operating above 100 GHz. It can be dynamically re-configured in real time to avoid interference to passive satellite sensing systems, enabling safe coexistence of active and passive users in this spectrum.
