The new digital switches made with graphite and boron nitride nanotube can better control current

The scientists combine graphene with nitride nanotubes to make a new hybrid digital switch that can be used as the basic
element to control current in electronic products. The future promises to make transistors that are not silicon semiconductor,
making computers, mobile phones, medical devices and other electronics work faster and with smaller size. Graphene can
be "transformed" into a variety of unique materials. Nitride nanotubes can also be processed into various biological and
physical materials, but the two materials do not have a place in the electronics world. The electrons in the graphene
conductor are released too fast to control the current. The boron nitride nanotubes are not even electrically conductive
insulators when they exist alone.
Physicist network reported, Michigan tech university physicist Ye Yujin, led his team to the chemical structure of these two
materials, find its don't match, finally successfully developed a new hybrid digital switch. They etched out many small
pinholes at the monolayer graphene surface, and then to the pinhole in the introduction of boron nitride nanotubes, mixed
material looks like a layer of the fused bark with irregular thin hair.
Due to the mismatch of the chemical structure, the joint points of the two materials will not match. The graphene thin layer
conducts electricity quickly, while the atomic structure in the nanotube prevents the electron flow, so the mixing material
has a gap (barrier). These gaps become the key to regulating and preventing electronic flow. The contact points between the
two materials are called "heterogenous knots", which are digital switches.
The research proves that the new hybrid switch has a higher conversion coefficient, and its switching speed is several
orders of magnitude higher than that of existing graphene converters, which will accelerate the development of electronic
products and computers
The new hybrid material also addresses two of the current silicon semiconductors in transistors: they can't be smaller and
have a lot of heat. In addition, the new digital switch can avoid the problem of electron flow dispersion due to the matching
of the same atomic arrangement of the graphene and nitride nanotubes. Electrons only flow in the same direction to make a
larger current, but often electrons go off in the same direction, greatly reducing the current's strength and speed. The new
hybrid switch can control the direction of the electrons in the high-speed current and get the offset electrons back on track.
