Atomically thin material could cut need for transistors in half
- gvb 7y ago[T]hey slipped in a layer of graphene next to the MoS2. Graphene is capable of capturing some of the conducting electrons and storing them. If the transistor ends up in the "on" state, enough of these electrons will spill over into the graphene that it will have sufficient charge to keep it in the "on" state. And that's where the transistor will stay until the electrons are specifically drained from the graphene. In this way, the graphene can act as a one-bit memory, storing the results of one past operation until the device is reset. Having non-volatile memory cells in the 4nm range and possibly without the wear-out mechanisms of current "flash" type memory would be HUGE.
- flqn 7y agoI like how "MoS2" (molybdenum disulfide) is sorta like "MOS 2" (could be read as Metal Oxide Semiconductor, 2). Kind of an accidental pun, almost :)
