Before and After Micropillars (image) DOE/SLAC National Accelerator Laboratory Caption This image shows a cross-polarized optical micrograph comparing a sample of an organic semiconducting film created without micropillars (top) and with micropillars (bottom) at scales of both one millimeter and 50 micrometers. Note the uniformity of the crystals in the bottom image as compared to in the top image. Credit Credit: Y. Diao et al.
