E-Mail Credit: Muqing Yu PITTSBURGH--It has long been a dream to invent new materials from the "top down" choosing which atoms go where to engineer properties of interest. A technique created by researchers out of the Department of Physics and Astronomy enables them to "sketch" patterns of electrons into a programmable quantum material--lanthanum aluminate/strontium titanate or "LAO/STO". Using this approach, they can create quantum devices and with feature sizes comparable to the spacing between electrons, and even "sketch" artificial lattices for electrons to traverse, with extremely hi...
