    摘要: According to example embodiments a transistor includes a channel layer on a substrate, a first channel supply layer on the channel, a depletion layer, a second channel supply layer, source and drain electrodes on the first channel supply layer, and a gate electrode on the depletion layer. The channel includes a 2DEG channel configured to generate a two-dimensional electron gas and a depletion area. The first channel supply layer corresponds to the 2DEG channel and defines an opening that exposes the depletion area. The depletion layer is on the depletion area of the channel layer. The second channel supply layer is between the depletion layer and the depletion area.

    摘要: According to an example embodiment, a power device includes a substrate, a nitride-containing stack on the substrate, and an electric field dispersion unit. Source, drain, and gate electrodes are on the nitride-containing stack. The nitride-containing stack includes a first region that is configured to generate a larger electric field than that of a second region of the nitride-containing stack. The electric field dispersion unit may be between the substrate and the first region of the nitride-containing stack.
