ABSTRACT:
Composite films formed from blends of semiconducting and insulating materials that phase separate on patterned substrates are provided. Phase separation provides isolated and encapsulated areas of semiconductor on the substrate. Processes for preparing and using such composite films are also provided, along with devices including such composite films.
