Abstract: Methods and apparatus for characterizing a sample in situ as to both its mechanical and optical characteristics. The apparatus comprises a reflective microscope with a concave primary mirror and a convex secondary mirror sharing a common optical axis, and an actuator vignetted by the convex secondary mirror for applying a force to a nanoprobe in a direction having a component along the common optical axis. The apparatus may addition include a source for generating an illuminating beam, a detector, and a processor for forming an image based on a signal provided by the detector.

Abstract: Provided are methods of patterning block copolymer (BCP) films with independent control of the size, periodicity and morphology of the resulting nanoscale domains. Also disclosed are BCP patterns having discrete areas of different self-assembled BCP thin films on a surface, the BCP thin films differing in one or more of molecular weight (MW), composition, morphology, and feature size. In some implementations, multiple BCPs with different MWs can be printed onto a single substrate, thereby providing access to patterns with diverse geometries and feature sizes. The printing approaches can be applied to various BCP chemistries, morphologies and directed self-assembly (DSA) strategies. Also provided are methods of forming BCP thin films on patterns of polymer brushes formed by electrohydrodynamic printing. The methods involve direct, high resolution electrohydrodynamic delivery of random copolymer brushes as surface wetting layers to control the geometries of nanoscale domains in spin-cast and printed BCPs.

Abstract: Provided are various methods and devices for electrohydrodynamic (E-jet) printing. The methods relate to sensing of an output current during printing to provide control of a process parameter during printing. The sensing and control provides E-jet printing having improved print resolution and precision compared to conventional open-loop methods. Also provided are various pulsing schemes to provide high frequency E-jet printing, thereby reducing build times by two to three orders of magnitude. A desktop sized E-jet printer having a sensor for real-time sensing of an electrical parameter and feedback control of the printing is provided.
