A tube-in-a-tube semiconductor

open access: yes2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD), 2016
Atomically-thin materials such as single-walled carbon nanotubes and graphene are prone to chemical attack because all of the constituent atoms are exposed. Here we describe progress from our lab in the synthetic creation of a tube-in-a-tube (Tube⁁2) semiconductor and their first applications in the electrical detection of small molecules and ...
