Oxygen ion conductors are crucial for enhancing the efficiency of various clean energy technologies, including fuel cells, batteries, electrolyzers, membranes, sensors, and more. I…
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…
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,…
Computational Discovery of Fast Interstitial Oxygen Conductors
Jun Meng, Md Sariful Sheikh, Ryan Jacobs +4
New highly oxygen-active materials may enhance many energy-related technologies by enabling efficient oxygen-ion transport at lower temperatures, e.g., below 400 Celsius. Interstit…
Triclinic BiFeO3: A room-temperature multiferroic phase with enhanced magnetism and resistivity
Md Sariful Sheikh, Tushar Kanti Bhowmik, Alo Dutta +3
The magnetic and transport properties of BiFeO3/La2NiMnO6 (BFO/LNMO) composite have been investigated both experimentally and theoretically. Unlike the normal rhombohedral (R3c) ph…
