Researchers have developed a TiO2/MoSe2 heterojunction sensor that can rapidly and sensitively detect sulfur dioxide, crucial ...

namely molybdenum diselenide (MoSe 2) and tungsten diselenide (WSe 2). "To overcome the limitations of silicon-based semiconductors and sustain progress, the industry must transition to ...

There are 2D materials that are good semiconductors, though, like molybdenum disulfide or tungsten diselenide. “They offer very stable electrical performance even below one nanometer,” Kim said.
