Scientists combine graphene and boron nitride nanotubes to create a new hybrid digital switch that can be used as a fundamental component in electronic control. In the future, it is expected to make transistors without silicon semiconductors, making computers, mobile phones, medical equipment and other electronic products faster and smaller. Graphene can be “transformed†into a variety of unique materials. Boron nitride nanotubes can also be processed into a variety of biological and physical materials, but these two materials have not gained a place in the electronics industry: electron release in graphene conductors Too fast to control the current; even if the boron nitride nanotubes are present alone, they are not electrically conductive. According to a report by the physicist organization network, physicist Ye Yujin of the Michigan Institute of Technology led his team to amplify the chemical structure of the above two materials to find its mismatch, and finally successfully developed a new hybrid digital switch. They etched many small pinholes on the surface of the monolayer graphene and then introduced boron nitride nanotubes into the pinhole. The fused mixture looks like an irregular thin hair on a layer of bark. Due to the mismatch of the chemical structure, the energy gap mismatch occurs at the junction of the two materials: the thin layer of graphene conducts fast, and the atomic structure in the nanotube prevents the flow of electrons, so the mixed material has the gap difference. base). These gaps are the key to regulating and preventing the flow of electrons. The point of contact between the two materials is called a "heterojunction" and these heterojunctions are digital switches. Studies have shown that the new hybrid switch has a higher conversion factor, and its switching speed is several orders of magnitude higher than existing graphene converters, which will accelerate the development of electronic products and computers. The new hybrid materials can also solve the two short plates of silicon semiconductors in current transistors: they cannot be smaller and generate a lot of heat. In addition, since graphene and boron nitride nanotubes have the same atomic arrangement, ie, site matching, the new digital switch can also avoid the problem of electron flow dispersion. Electrons only flow in the same direction to make a larger current, but often electrons deviate from the original direction, greatly reducing the intensity and speed of the current. The new hybrid switch can control the direction of the electrons in the high-speed forward current, allowing the deviating electrons to return to the right track. Concerned about surprises Bolts
