A) LG1/LG2 = 70 nm/1850 nm, (b) LG1/LG2 = 70 nm/350 nm. The grating geometry reflects the emission spectra. 5 THz vs. Vds for the sample with LG1/LG2 = 70 nm/1850 nm, showing threshold behavior and super-linear (near quadratic) dependence on Vds. Two solid lines in (a) are calculated results for emissions from thermally excited plasmons at electronic temperatures of 310K and 320K. (after Ref. ) Fig. 9. FTIR measured emission spectra for a semiconducting grating-gate sample with LG1/LG2 = 150 nm/1850 nm at room temperature.

It has been demonstrated that this devices’ transconductance increases with applied drain voltage. This supports the notion that as the device is scaled, transconductance will improve not only by reducing gatechannel distance, but also by shortening the channel length. The highly configurable nature of the Ballistic Deflection Transistor makes it suitable for a wide variety of applications. Acknowledgments The authors would like to thank Daniel Purdy for his comments and contributions to the work as well as for providing the initial support of this project under ONR award N000140510052.

14(b). These results are attributed to the emission of coherent electromagnetic radiation stimulated by photo-induced plasmon instability. 1 µW. We confirmed that the emission spectrum traces the 2D plasmonic dispersion relation in terms of its 2D electron density and the cavity size8, 9. Fig. 14.
