Multilayer borophene patched PEDOT:PSS p-n junctions for medical x-ray detection
In this study, we combine n-type PEDOT:PSS with multilayer borophene nanosheets (BNSs) at defined weight ratios. As borophene is a material that behaves like a p -type, we observe the formation of localized p-n junctions along the organic–inorganic hybrid structures, as evidenced by current–voltage…
