3D semiconductor particles offer 2D properties

Journal Reference: Xianwen Mao, Peng Chen. Inter-facet junction effects on particulate photoelectrodes. Nature Materials, 2021; DOI: 10.1038/s41563-021-01161-6 Three-dimensional semiconductor particles have an edge, too — many of them — given their geometrically varied surfaces. Cornell researchers have discovered that the junctures at these facet edges have 2D properties, which can be leveraged for photoelectrochemical processes … Read more
