Scalable method to manufacture thin film transistors achieves ultra-clean interface for high performance, low-voltage device operation
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.
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.
Chemists and engineers collaborate on process that washes away nonconductive side chains from a robust polymer backbone to create a powerful conductive plastic.
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.
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.
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.
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
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 ...
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.
Phosphors or QDs for color conversion in LCD and microLED ? Which will win? This is an evolving technology space to watch. Here, it is shown that phosphor technology is evolving, enabling not just red but also green narrowband color conversation with small particle sizes compatible with microLEDs
Augmented reality (AR) head-up displays (HUDs) are widely considered to be the future of connected vehicles, but more human-centred studies are needed to assess the impact of AR on the driver while operating a vehicle on public roads, say Cambridge researchers.
In this episode, we talk about how performance limitations of current microchips are being addressed by utilizing novel materials like graphene and bioinspired designs to address the needs of next generation computing and electronics.
In a discovery that could speed research into next-generation electronics and LED devices, a University of Michigan research team has developed the first reliable, scalable method for growing single layers of hexagonal boron nitride (hBN) on graphene.
In this episode, we talk about how a radical change in plastic composition can significantly minimize waste when recycling plastics without compromising material properties and a first of its kind smart fabric with customizable properties which serves as the first step towards a whole new market
