Holmes Research Group of the CEMS DepartmentTPBi is an organic semiconductor used in the fabrication of OLEDs. Studies have shown that the outcoupling efficiency of OLEDs can be greatly increased by introducing a periodic corrugation in the layers of the device. This study explores the crystallization of TPBi, which forms platelet-like crystals with a sinusoidal pattern upon annealing. The factors that influence the d-spacing of the pattern and the mechanisms that give rise to it are explored and discussed.enScholarly Text or Essay
