Led by Prof. Becky Peterson, the research focuses on a category of materials important for low power logic operations, high pixel density screens, touch screens, and haptic displays.

Scalable method to manufacture thin film transistors achieves ultra-clean interface for high performance, low-voltage device operation

ETH researchers have developed a modular system for the simple and inexpensive production of security inks. It is based on polymers and could also be used in solar power plants and screens in the future.

Entire colour palette of inexpensive fluorescent dyes

Chemists and engineers collaborate on process that washes away nonconductive side chains from a robust polymer backbone to create a powerful conductive plastic.

Going Back to Basics Yields a Printable, Transparent Plastic That's Highly Conductive

A unique new approach of printing functional materials with unparallel precision and repeatability. Technology called Ultra-Precise Deposition (UPD) is a nanodispensing method capable to print high density and high viscous materials with the resolution down to 1 µm in feature size and with high ratio of width to height after single pass. For this method material extrusion is controlled by a pressure, which means it is not supported with high electric field. Thanks to this there are no limitation if the substrate is conductive or dielectric.

Ultra-Precise Deposition for the Fabrication of Next-Generation MicroLED and QD-LED Displays

Prof. Zetian Mi’s team are the first to achieve high-performance, highly stable green micro-LEDs with dimensions less than 1 micrometer on silicon, which can support ultrahigh-resolution full-color displays and other applications.

Breakthrough in green micro-LEDs for augmented-mixed reality devices

Columbia engineers invent a flat lens that exclusively focuses light of a selected color—it appears entirely transparent until they shine a beam of light with the correct wavelength onto it, when the glass turns into a lens.

Optical Magic: New Flat Glass Enables Optimal Visual Quality for Augmented Reality Goggles

Researchers have designed smart, colour-controllable white light devices from quantum dots, tiny semiconductors just a few billionths of a metre in size, which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light

Quantum Dots That Produce Smart White Lighting For Daylight

Why can microLED technology can help narrow the energy gap in electronic devices? The first slide shows the battery gap- Ahmed (Intel) has collected data by year showing that power demand of phones far exceeds the power supply level of batteries, creating a "battery gap" which ...

Why can microLED technology help narrow the energy gap in electronic devices?

Researchers at Columbia University and Politecnico di Milano have used an atomically thin material to build a device that can change the color of laser beams. Their microscopic device—a fraction of the size of conventional color converters—may yield new kinds of ultra-small optical circuit chips and advance quantum optics.
