    摘要: A Graphene Flash Memory (GFM) device is disclosed. In general, the GFM device includes a number of memory cells, where each memory cell includes a graphene channel, a graphene storage layer, and a graphene electrode. In one embodiment, by using a graphene channel, graphene storage layer, and graphene electrode, the memory cells of the GFM device are enabled to be scaled down much more than memory cells of a conventional flash memory device. More specifically, in one embodiment, the GFM device has a feature size less than 25 nanometers, less than or equal to 20 nanometers, less than or equal to 15 nanometers, less than or equal to 10 nanometers, or less than or equal to 5 nanometers.

    摘要: A carrier-mediated magnetic phase change spin transistor is disclosed. In general, the spin transistor includes a Dilute Magnetic Semiconductor (DMS) channel and a gate stack formed on the DMS channel. The gate stack includes a multiferroic gate dielectric on the DMS channel, and a gate contact on a surface of the multiferroic gate dielectric opposite the DMS channel. The multiferroic gate dielectric is formed of a multiferroic material that exhibits a cross-coupling between magnetic and electric orders (i.e., magnetoelectric coupling), which in one embodiment is BiFeO3 (BFO). As a result, the multiferroic material layer enables an electrically modulated magnetic exchange bias that enhances paramagnetic to ferromagnetic switching of the DMS channel. The DMS channel is formed of a DMS material, which in one embodiment is Manganese Germanium (MnGe). In one embodiment, the DMS channel is a nanoscale DMS channel.
