New Chemistry research: Black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors. This is a schematic of the "puckered honeycomb" crystal structure of black phosphorus. Credit: Vahid Tayari/McGill University Published in the journal: Nature Communications , the researchers are utilising black phosphorus as a material to pack more transistors on a chip, making them more energy-efficient. The work is a result of a multidisciplinary collaboration among Szkopek's nanoelectronics research group, the nanoscience lab of McGill Physics Prof. Guillaume Gervais, and the nanostructures research group of Prof. Richard Martel in Université de Montréal's Department of Chemistry. Reporting on their finds, the scientists at McGill University, have found that when electrons move in a phosphorus transistor, they do so only in two dimensions. This will help in designing new energy-efficient t
