Direct evidence of low work function on SrVO cathode using thermionic electron emission microscopy and high-field ultraviolet photoemission spectroscopy
Md Sariful Sheikh, Lin Lin, Ryan Jacobs +5
Perovskite SrVO has recently been proposed as a novel electron emission cathode material. Density functional theory (DFT) calculations suggest multiple low work function surfac…

Class-E, Active Electrically-Small Antenna for High-Power Wideband Transmission at the High-Frequency (HF) Band
Nathan Strachen, John H. Booske, Nader Behdad
Antennas operating at the high-frequency (HF) band (3-30 MHz) are frequently electrically small due to the large wavelength of electromagnetic waves (10-100 m). However, the bandwi…

Time-dependence of SrVO thermionic electron emission properties
Md Sariful Sheikh, Ryan Jacobs, Dane Morgan +1
Thermionic electron emission cathodes are critical components of various high power and high frequency vacuum electronic devices, electron microscopes, e-beam lithographic devices,…
