The thin films of organic semiconductor anthracen were fabricated on SiO2 substrate by traditionary vacuum sublimation.The surface morphology,nucleation and growth of anthracen thin film were studied by observing a series of samples grown under different depositing times with SEM and AFM.It indicates that the growth mode of anthracen deposited onto SiO2substrates follows the Volmer-Weber mode,namely,firstly,anthracen molecules form lots of three-dimensional island-like anthracen crystal nuclei,and nuclei gr...
