A new method for aligning light‐emitting materials is reported here: The friction transfer technique was used to produce the poly(tetrafluoroethylene) surface shown in the Figure. The surface has a high density of ridges and grooves with height variations on the ten‐nanometer scale, and thin films with high optical quality and controllable thickness were readily obtained. Polarized LEDs fabricated on such surfaces show high dichroic ratios.
