Reconfigurable Logic Operation of MoTe2 Homojunction Enabled by Staggered Double‐Sided Contacts

Electron, EarlyView.
A gap adjacent to an electrode in the MoTe2 SDC transistor enables polarity reconfiguration, switching between p‐type and n‐type depending on bias polarity. This reconfiguration is ensured when the absolute bias voltage is less than the gate voltage, yielding a near‐ideal subthreshold swing of 67.6 mV/dec and on/off ratios of 104–106.

Boron Nitride Nanomesh

Science, 2004
A highly regular mesh of hexagonal boron nitride with a 3-nanometer periodicity and a 2-nanometer hole size was formed by self-assembly on a Rh(111) single crystalline surface. Two layers of mesh cover the surface uniformly after high-temperature exposure of the clean rhodium surface to borazine (HBNH) 3 .

Boron Nitride Nanotubes

Science, 1995
The successful synthesis of pure boron nitride (BN) nanotubes is reported here. Multi-walled tubes with inner diameters on the order of 1 to 3 nanometers and with lengths up to 200 nanometers were produced in a carbon-free plasma discharge between a BN-packed tungsten rod and a cooled copper electrode.

Junctions between a boron nitride nanotube and a boron nitride sheet

Nanotechnology, 2008
For future nanoelectromechanical signalling devices, it is vital to understand how to connect various nanostructures. Since boron nitride nanostructures are believed to be good electronic materials, in this paper we elucidate the classification of defect geometries for combining boron nitride structures.
