Imaging graphene moiré superlattices via scanning Kelvin probe microscopy
Junxi Yu, Rajiv Giridharagopal, Yuhao Li +5
Moiré superlattices in van der Waals heterostructures are gaining increasing attention because they offer new opportunities to tailor and explore unique electronic phenomena when s…
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…
