- 論文の詳細を見る
We studied the sublimation of tetracene single crystals under vacuum and 1 atm inert gas to develop the surface cleaning technique for organic semiconductors. It was found that the microscopic sublimation behavior is strongly dependent on the gas pressure. Nanometer-scale roughening was observed after heating in vacuum, and layer-by-layer sublimation was observed under 1 atm Ar gas. Reflection high energy electron diffraction analysis of the topmost surface showed streak patterns, indicating that surface contaminants were successfully removed.
