Devices with active organic layers are of great interest recently due to their less energy consumable process and potential low cost. However, the future success of these interesting materials in applications will strongly depend on fabrication processes that include patterning. We present a general method to pattern organic molecules by template-directed nucleation control using organic molecular beam deposition. Fully sites selective growth of organic molecules can be controlled at optimized conditions. We use simple Lennard-Jones (LJ) pair potentials to mimic the molecular interactions. The simulation results have good agreements with experimental data. This technique can be applied to fabricate large area uniform organic devices.
