Optical tuning of the diamond Fermi level measured by correlated scanning probe microscopy and quantum defect spectroscopy
Christian Pederson, Rajiv Giridharagopal, Fang Zhao +4
Quantum technologies based on quantum point defects in crystals require control over the defect charge state. Here we tune the charge state of shallow nitrogen-vacancy and silicon-…
Kinetic Suppression of Photoinduced Halide Migration in Wide Bandgap Perovskites via Surface Passivation
Farhad Akrami, Fangyuan Jiang, Rajiv Giridharagopal +1
In this work, we study the kinetics of photoinduced halide migration in FACsPb(IBr) wide (~1.69 eV) bandgap perovskites and show halide migratio…
Why accumulation mode organic electrochemical transistors turn off much faster than they turn on
Jiajie Guo, Shinya E. Chen, Rajiv Giridharagopa +7
Understanding the factors underpinning device switching times is crucial for the implementation of organic electrochemical transistors (OECTs) in neuromorphic computing and real-ti…
Surface Passivation Suppresses Local Ion Motion in Halide Perovskites
Justin Pothoof, Robert J. E. Westbrook, Rajiv Giridharagopal +2
We use scanning probe microscopy to study ion migration in the formamidinium (FA)-containing halide perovskite semiconductor in the pres…
