However, the experimental development of a photoelectric system capable of combining atomic-level visualization with simultaneous electrical current measurement with picoampere-precision still remains a great challenge due to light-induced drift while imaging and noise in the electrical components due to background current. Herein, we report a novel photoelectric TEM holder integrating an LED light source covering the whole visible range, a shielding system to RSC advances948-953https://www.ebi.ac.uk/biostudies/studies/S-EPMC9077018biostudies-literatureSimultaneous atomic-level visualization and high precision photocurrent measurements on photoelectric devices by <i>in situ</i> TEM.PMC9077018Sun LDong HXu TXu FHe LSun ZZhang QWu XfalseSimultaneous atomic-level visualization and high precision photocurrent measurements on photoelectric devices by <i>in situ</i> TEM.Herein, a novel <i>in situ</i> transmission electron microscopy (TEM) method that allows high-resolution imaging and spectroscopy of nanomaterials under simultaneous application of different stimuli, such as light excitation, has been reported to directly explore structure-activity relationships targeted towards device optimization.
