Transit-time resonances enabling amplification and generation of terahertz radiation in periodic graphene p-i-n structures with the Zener-Klein interband tunneling
V. Ryzhii, M. Ryzhii, V. Mitin +2
The Zener-Klein (ZK) interband tunneling in graphene layers (GLs) with the lateral n-i-n and p-i-n junctions results in the nonlinear I-V characteristics that can be used for the r…
Graphene vertical cascade interband terahertz and infrared photodetectors
V. Ryzhii, T. Otsuji, M. Ryzhii +5
We propose and evaluate the vertical cascade terahertz and infrared photodetectors based on multiple-graphene-layer (GL) structures with thin tunnel barrier layers (made of tungste…
Graphene vertical hot-electron terahertz detectors
V. Ryzhii, A. Satou, T. Otsuji +3
We propose and analyze the concept of the vertical hot-electron terahertz (THz) graphene-layer detectors (GLDs) based on the double-GL and multiple-GL structures with the barrier l…
Observation of Amplified Stimulated Terahertz Emission from Optically Pumped Epitaxial Graphene Heterostructures
Taiichi Otsuji, Hiromi Karasawa, Tsuneyoshi Komori +5
We experimentally observe the fast relaxation and relatively slow recombination dynamics of photogenerated electrons/holes in an epitaxial graphene-on-Si heterostructure under pump…
Epitaxial Graphene on Silicon toward Graphene-Silicon Fusion Electronics
Hirokazu Fukidome, Ryota Takahashi, Yu Miyamoto +8
Graphene is a promising contender to succeed the throne of silicon in electronics. To this goal, large-scale epitaxial growth of graphene on substrates should be developed. Among v…
