New Transistor’s Superlative Properties could have Broad Electronics Applications

New transistor's superlative properties could have broad electronics applications
Caption: Schematic showing the crystal structure of the boron nitride key to a new ferroelectric material that MIT researchers and colleagues have used to build a transistor with superlative properties. The schematic shows how the structure can change as two ultrathin layers of boron nitride slide past each other upon application of an electric field. The P stands for polarization, or negative/positive charge. Credit: Ashoori and Jarillo-Herrero labs

In 2021, a team led by MIT physicists reported creating a new ultrathin ferroelectric material, or one where positive and negative charges separate into different layers. At the time, they noted the material’s potential for applications in computer memory and much more...

Could Black Phosphorus be the next Silicon?

New material could make it possible to pack more transistors on a chip. When electrons move in a phosphorus transistor, they do so only in 2D. Thus black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors. “Transistors work more efficiently when they are thin, with electrons moving in only two dimensions,” says a/Prof Szkopek, “Nothing gets thinner than a single layer of atoms.”

In 2004, physicists at the University of Manchester first isolated and explored graphene and now there are other 2D materials like black phosphorus, a form of phosphorus similar to graphite and can be separated easily into single atomic layers, ie phosphorene...
