What They Say
Science Daily said that a group led by University of Minnesota Professor K. Andre Mkhoyan has made a discovery that combines transparency and conductivity in perovskite materials. The group found metallic line defects in barium stannate (BaSnO3), a perovskite material. Mkhoyan said
“The conductive nature and preferential direction of these metallic line defects mean we can make a material that is transparent like glass and at the same time very nicely directionally conductive like a metal”
“We easily spotted these line defects in the high-resolution scanning transmission electron microscopy images of these BaSnO3 thin films because of their unique atomic configuration and we only saw them in the plan view,”
said Hwanhui Yun, a graduate student in the Department of Chemical Engineering and Materials Science and a lead author of the study.
There is a paper on this topic in Science Advances.
What We Think
Transparency and conductivity are, indeed, a very useful combination. These days, however, it would really be helpful to have flexibility as well! (BR)
