Field-Effect Transistor and Photo-Transistor of Narrow-Band-Gap Nanocrystal Arrays Using Ionic Glasses

Inter-band Tunnel Transistor Architecture using Narrow Gap Semiconductors

The inter-band tunnel transistor (TFET) architecture features a subkT/q sub-threshold slope operation and can potentially support high ION/IOFF ratios over small gate voltages. Based on twodimensional numerical simulations, we investigate TFET in various material systems ranging from silicon to indium arsenide. TFET performance can be enhanced when heterojunctions are employed at the source sid...

Graphene field effect transistor as a radiation and photo detector

We exploit the dependence of the electrical conductivity of graphene on a local electric field, which can be abruptly changed by charge carriers generated by ionizing radiation in an absorber material, to develop novel highperformance radiation sensors for detection of photons and other kinds of ionizing radiation. This new detection concept is implemented by configuring graphene as a field eff...

Atomic-Monolayer MoS2 Band-to-Band Tunneling Field-Effect Transistor.

The experimental observation of band-to-band tunneling in novel tunneling field-effect transistors utilizing a monolayer of MoS2 as the conducting channel is demonstrated. Our results indicate that the strong gate-coupling efficiency enabled by two-dimensional materials, such as monolayer MoS2 , results in the direct manifestation of a band-to-band tunneling current and an ambipolar transport.

Hydrogenated monolayer graphene with reversible and tunable wide band gap and its field-effect transistor

Graphene is currently at the forefront of cutting-edge science and technology due to exceptional electronic, optical, mechanical, and thermal properties. However, the absence of a sizeable band gap in graphene has been a major obstacle for application. To open and control a band gap in functionalized graphene, several gapping strategies have been developed. In particular, hydrogen plasma treatm...
