摘要： Methods and systems for emitting light from electrically biased graphene are provided. An exemplary method of generating a light emission from graphene includes suspending a graphene membrane using at least one mechanical clamp and providing a current to the graphene membrane to establish a source-drain bias voltage along the graphene membrane.

摘要： A radio frequency (RF) receiver including a baseband circuitry. The baseband circuitry can include a graphene nano-electro-mechanical (GNEMS) based system, a receiver, and a front-end mixer. The GNEMS based system can include a source, a drain, a gate and a nano-scale suspended graphene resonator. The graphene resonator can be suspended between the source and the drain. The receiver circuitry can be disposed on the baseband and configured to receive an RF signal. The front-end mixer can be disposed between the GNEMS based system and the receiver circuitry. The baseband circuitry can be configured such that an incoming signal sees frequency selective impedance at the receiver circuitry.

摘要： A nano-electro-mechanical systems (NEMS) oscillator can include an insulating substrate, a source electrode and a drain electrode, a metal local gate electrode, and a micron-sized, atomically thin graphene resonator. The source electrode and drain electrode can be disposed on the insulating substrate. The metal local gate electrode can be disposed on the insulating substrate. The graphene resonator can be suspended over the metal local gate electrode and define a vacuum gap between the graphene resonator and the metal local gate electrode.
