Polymer transfer printing: Application to layer coating, pattern definition, and diode dark current blocking

Fabrication of polymer multilayer sructures has previously been difficult t to achieve due to the need for L. solvent orthogonality to ensure that sequential deposition does not damage any underlying layers. In this paper we report an alternative approach based on a stamp transfer printing process. We demonstrate its suitability for uniform and patterned multilayer deposition (c.f. figure) and use it as a means to engineer enhanced performance photodiode structures.
