WebHerein, 2D porous carbon nitride (PCN) is synthesized, followed by the in situ growth of 1D WO on the PCN to realize a step-scheme (S-scheme) heterojunction. When WO and PCN are composited, the difference between the Fermi levels of WO and PCN leads to electron migration, which balances the Fermi levels of WO and PCN. WebThe aim of this project is to bridge the long-established knowledge on magnetic insulators with today’s expertise on spintronics and measurement techniques. I will exploit the highly tunable properties of magnetic insulators to achieve efficient magnetization control by electrical means in various schemes.
