Light-dependent Impedance Spectra and Transient Photoconductivity in a Ruddlesden-Popper 2D Lead-halide Perovskite Revealed by Electrical Scanned Probe Microscopy and Accompanying Theory
Ali Moeed Tirmzi, Ryan P. Dwyer, Fangyuan Jiang +1
Electric force microscopy was used to record the light-dependent impedance spectrum and the probe transient photoconductivity of a film of butylammonium lead iodide, BAPbI$_{…
Substrate-dependent Photoconductivity Dynamics in a High-efficiency Hybrid Perovskite Alloy
Ali Moeed Tirmzi, Jeffrey A. Christians, Ryan P. Dwyer +2
Films of (FAMACs)Pb(IBr) were grown over TiO, SnO, ITO, and NiO. Film conductivity was interrogated by me…
Lagrangian and impedance spectroscopy treatments of electric force microscopy
Ryan P. Dwyer, Lee E. Harrell, John A. Marohn
Scanning probe microscopy is often extended beyond topographic imaging to study electrical forces and sample properties, with the most widely used experiment being frequency-modula…
Vector Electric Field Measurement via Position-Modulated Kelvin Probe Force Microscopy
Ryan P. Dwyer, Louisa M. Smieska, Ali Moeed Tirmzi +1
High-quality spatially-resolved measurements of electric fields are critical to understanding charge injection, charge transport, and charge trapping in semiconducting materials. H…
