Hi everybody, I need to deposit P3HT (a conducting polymer) from disolution in a 10cmx10cm substrate, and I need to control de thickness of the layer around 100-200nm. We used to make it by spincoating with smaller substrates, now I would like to test other techniques (doctor blade, inkjet printing...)., but I dont know if it is possible with such thin layers. Any suggestions? Also, for the spincoating we used toluene for the solution, but with continuous processes, should we change the solvent to another one with more viscosity? Thank you very much in advance. Rafael García Valverde Dept. Electrónica, Tecnología de Computadores y Proyectos (ETSIT) Electronics, Computer Technology and Projects.
