Mapping Intrinsic Electromechanical Responses at the Nanoscale via Sequential Excitation Scanning Probe Microscopy Empowered by Deep Data
Boyuan Huang, Ehsan Nasr Esfahani, Jiangyu Li
Ever increasing hardware capabilities and computation powers have made acquisition and analysis of big scientific data at the nanoscale routine, though much of the data acquired of…
Piezoelectricity of Atomically Thin WSe2 via Laterally Excited Scanning Probe Microscopy
Ehsan Nasr Esfahani, Terrance Li, Bevin Huang +2
Lattices of odd-layered two-dimensional (2D) transition metal dichalcogenides (TMDs) such as WSe2 are non-centrosymmetric, and thus could possess linear piezoelectricity that is at…
Ferroic Domains of Alternating Polar and Nonpolar Orders Regulate Photocurrent in Single Crystalline CH3NH3PbI3 Films Self-grown on FTO/TiO2 Substrate
Boyuan Huang, Guoli Kong, Ehsan Nasr Esfahani +10
Photovoltaic conversion efficiency (PCE) of halide perovskite solar cells has risen spectacularly, yet the very crystalline structure of CH3NH3PbI3 remains ambiguous after extensiv…
Quardratic Electromechanical Strain in Silicon Investigated by Scanning Probe Microscopy
Junxi Yu, Ehsan Nasr Esfahani, Qingfeng Zhu +4
Piezoresponse force microscopy (PFM) is a powerful tool widely used to characterize piezoelectricity and ferroelectricity at the nanoscale. However, it is necessary to distinguish…
Imaging Ferroelectric Domains via Charge Gradient Microscopy Enhanced by Principal Component Analysis
Ehsan Nasr Esfahani, Xiaoyan Liu, Jiangyu Li
Local domain structures of ferroelectrics have been studied extensively using various modes of scanning probes at the nanoscale, including piezoresponse force microscopy (PFM) and…
Resolving Local Electrochemistry at the Nanoscale via Electrochemical Strain Microscopy: Modeling and Experiments
Ahmad Eshghinejad, Ehsan Nasr Esfahani, Chihou Lei +1
