An effective route is developed to fabricate ultrathin rhenium diselenide (ReSe2) nanosheets anchored on reduced graphene oxide (rGO) nanoflakes (ReSe2@rGO). When the ReSe2@rGO is used as an anode material in the potassium‐ion batteries (PIBs), the graphene offers a conductive matrix to buffer the volume alteration during repeated K+ insertion/extraction cycles. The stable interfacial connection...
Single-walled carbon nanotubes (SWCNTs) hold vast potential for future electronic devices due to their outstanding properties, however covalent functionalization often destroys the intrinsic properties of SWCNTs, thus limiting their full potential. Here, we demonstrate the fabrication of a functionalized graphene/semiconducting SWCNT (T@fG) heterostructured thin film transistor as a chemical sensor...
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 implications on biological sensing. A Tube⁁2 is equivalent...
