Our Research

Monolithically-Integrated Textile Electronics

Unlike conventional substrates, such as glass, PET or paper, textiles are 3D microscaffolds displaying roughness and texture on multiple length scales.
3D Scaffold

Conformal coating techniques are integral for directly growing nanostructured devices from textile substrates.
We perform a small variety of vapor phase polymerization reactions to create films of conjugated polymers inside a reduced-pressure hot wall reactor.
One such example is the oxidative chemical vapor polymerization of EDOT to create PEDOT.

This process creates stable, conformal films of a conducting polymer--PEDOT, in this case-- on arbitrary substrates, including various prewoven textiles.

PEDOT coated Fabrics

We use this vapor-phase deposition method to transform ordinary textiles into functional electronic devices. Our approach also minimizes the tremendous water pollution caused by traditional textile processing.
Some of our products are described below.

Textile/Thread Circuit Elements

We create highly-conductive fabrics and threads that are capable of acting as simple circuit elements while also being stable to wearing, laundering, ironing, stretching/tugging and rubbing.
Conductive Textiles

Activity-Tracking, Triboelectric Textiles

We use traditional textile manufacturing methods, such as knitting and weaving, to create fabric swatches that harvest mechanical energy to generate power!

Triboelectric Textiles

Smart Garments

We endeavor to seamlessly integrate electronic components, such as transistors, heating elements, diodes and capacitors into garments by coating familiar threads and clothing with electronically-active conjugated polymers.

Solar Harvesting Textiles

We are exploring multiple integrative approaches to create solar fabrics that preserve the breathability, pliability and durability of textiles.

Vapor Phase Organic Chemistry

A suite of vapor-phase polymerization reactions performed inside a reduced-pressure hot wall reactor, collectively termed xCVD, are the enabling methods we use to build novel devices. In xCVD, films are formed directly on the substrate of interest as vapors of a chemical agent and precursor (or monomer) are introduced into an evacuated reactor chamber simultaneously, whereupon a polymer is formed in situ that subsequently coats arbitrary substrates placed in the polymerization region. This method allows for conformal coating of rough surfaces, with features resolvable down to 100-200 nm. The modularity of this technique ensures that careful monomer choice will lead to the in situ film growth of a host of conductive polymers displaying varied optoelectronic properties.


Our current toolbox of xCVD reactions enable the fabrication of chemically well-defined thin films of p-doped PEDOT and proDOT, neutral poly(thiophene)s and poly(aniline)s onto arbitrary substrates with micro- and nano-scale features. We are working to expand our xCVD toolbox to include n-type conjugated polymer films and conductive polyradical films. Vapor phase chemical deposition of both metallic and semiconducting conjugated polymer and polyradical films are actively being explored.

Tuning the Optoelectronic Properties of Organic Crystals Using Graphene

Crystal orientation in organic thin films is one of the key parameters that determines interfacial energetics, absorption profiles and cross sections, exciton diffusion lengths, exciton dissociation efficiencies, and charge collection efficiencies. We use monolayer graphene to direct the crystal orientation of selected planar organic molecules, including p-type and n-type small-molecule semiconductors.

Lying-down orientation with π-stacking normal to the surface can be achieved with graphene templating. Additionally, graphene controls the out-of-plane alignment of all the molecules studied past the first monolayer and provides a driving force for confined in-plane growth.


Significant excitonic and electronic changes, including huge modulations in absorption profiles, total %light absorbed, Fermi levels, band edge values and CT state energies can be observed in the graphene-templated films, relative to films grown on oxide surfaces. Such changes can potentially increase the theoretical Voc expected for photovoltaic devices incorporating these templated films.

Subdiffraction Optical Lithography Enabled by Photochromes

Currently, nanomanufacturing is achieved via fast pattern-replication (nanoimprint lithography, optical-projection lithography, etc.) and is stymied by extremely slow pattern generation (scanning-electron-beam lithography). In other words, the time it takes to generate a new pattern is orders of magnitude longer than what it takes to simply replicate one.

Light offers significant advantages over charged particles for pattern generation. However, it suffers from one Achilles heel - diffraction. In the far field, the smallest focused spot that can be generated with light is limited to approximately half the wavelength.This, so called far-field diffraction limit or the Abbé limit, effectively prevents the use of long-wavelength photons (greater than 300nm) from patterning nanostructures less than 100 nm.

We have shown that optics, when combined with novel photochemistry, can result in deep sub-wavelength patterning with speeds that are far higher than with conventional approaches.


Our idea is to record the nanoscale pattern in an ultra-thin or monolayer film comprised of photochromic molecules. These molecules undergo photoswitching between two isomeric forms, A and B. When isomer A absorbs a photon of wavelength 1, it turns into isomer B. When B absorbs photon of wavelength 2, it turns back to A. The binary nature of the switching process ensures that sub-diffraction-limited regions of B interspersed in A are formed.

In addition, we design the photochromic molecules such that B can be selectively converted in an irreversible manner to form C via a “locking” step, which allows us to create 3D patterns. These advances in pattern generation, when combined with continuous replication technologies such as roll-to-roll nanoimprint lithography can enable a new paradigm in high throughput top-down nanomanufacturing. In other words, organic photochromes can change the traditional process flow currently used to manufacture electronics!
