Very High Channel Conductivity in Low-Defect AlN/GaN High Electron Mobility Transistor Structures
Low defect AlN/GaN high electron mobility transistor (HEMT) structures, with very high values of electron mobility (\u3e1800 cm2/V s) and sheet charge density (\u3e3×1013 cm−2), were grown by rf plasma-assisted molecular beam epitaxy (MBE) on sapphire ...

Field Emission Control via Work Function Modulation in Semimetallic Graphene Edge Cathodes
Graphene edge cathodes, with atomically sharp edges, high carrier mobility, and electrostatically tunable electronic structure, enable a nanoscale vacuum transistor whose off‐channel gate directly modulates the emitter work function. The device achieves gate‐tunable current saturation from 10 to 300 K, low leakage, and amplification behavior enabled by
