Electrically Switchable Circular Photogalvanic Effect in Methylammonium Lead Iodide Microcrystals

Yuqing Zhu, Ziyi Song, Rodrigo Becerra Silva +6

We investigate the circular photogalvanic effect (CPGE) in single-crystalline methylammonium lead iodide microcrystals under a static electric field. The external electric field ca…
