Abstract
The high degree of order in organic single crystals often leads to optimum charge transport properties and their robustness under high current density which is attractive for solid state lighting and laser technology. However, conventional method of single crystal growth based on physical vapour transport is unsuitable for device integration and large area applications. Here, we present a vacuum processed approach to prepare organic single crystals on inch sized substrates and integrate them into organic light emitting devices (OLED). The device performance are characterized in comparison to standard OLED based on amorphous materials.
