Polymer Transfer Printing: Application to Layer Coating, Pattern Definition, and Diode Dark Current Blocking

Fabrication of polymer multilayer structures has previously been difficult to achieve due to the need for 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.
