In this work we report on thin organic films grown by Hot Wall Epitaxy (HWE
). This technique allows the epitaxial growth close to the thermodynamic eq
uilibrium. The growing process strongly depends on the choice of the substr
ate and substrate temperature. We produced para-hexaphenyl (PHP) and PHP/C-
60 bilayers by HWE and characterized the samples by polarized luminescence
and photocurrent measurements.
