Today's circuit technology requires low-power transistors and diodes to extend Moore's law. While research has been focused on reducing power consumption of transistors, have not widely studied. Here, we report a low-power, thus steep-slope Schottky diode, with “cold metal” source. The barrier between metal electrode bulk MoS 2 enabled the diode behavior, IV curve originated from change in dens...

We report on the discovery of a mysterious ultra-steep spectrum (USS) synchrotron source in galaxy cluster Abell 2877. have observed with Murchison Widefield Array at five frequencies across 72-231 MHz and found to exhibit strong spectral curvature over this range as well steepest known spectra source, index central three frequency bands $\alpha = -5.97^{+0.40}_{-0.48}$. Higher radio observatio...
