1. A method of making transferable semiconductor structures, said method comprising the steps of:
- providing a multilayer structure comprising a plurality of functional layers and a plurality of release layers;
wherein said release layers are positioned between functional layers in said multilayer structure, and at least one functional layer comprises a plurality of semiconductor structures anchored to said multilayer structure by a heterogeneous anchor, a homogeneous anchor, or a heterogeneous and a homogeneous anchor; and
releasing at least a portion of said semiconductor structures from said multilayer structure by separating one or more of said release layers from one or more of said functional layer and separating said plurality of semiconductor structures from said anchors, thereby generating said transferable semiconductor structures.

Abstract
Provided are methods for making a device or device component by providing a multi layer structure having a plurality of functional layers and a plurality of release layers and releasing the functional layers from the multilayer structure by separating one or more of the release layers to generate a plurality of transferable structures. The transferable structures are printed onto a device substrate or device component supported by a device substrate. The methods and systems provide means for making high-quality and low-cost photovoltaic devices, transferable semiconductor structures, (opto-)electronic devices and device components.
