Trions are what scientists call “quasiparticles,” bundles of energy, electric charge and spin that zoom around inside semiconductors.   Trions were first observed in quantum wells in 1993 and shortly thereafter in GaAs-AlGaAs quantum wells. Trions were were predicted and found in the photoluminescence and absorption spectra of various optically …

Nanotechnology enables designing and creating structures and devices utilising extraordinary properties and behaviour of matter at very fine length scales – nanoscale level (10-9 m). Between 2001 and 2004, approximately 60 countries globally implemented national nanotechnology programmes. According to R.D Shelton, an international technology assessor, research and development in this …

The emerging field of printed electronics requires a suite of functional materials for applications including flexible and large-area displays, radio frequency identification tags, portable energy harvesting and storage, biomedical and environmental sensor arrays, and logic circuits.   To enable these technologies, functional materials must be integrated with suitable patterning technologies, …

Neutrinos are some of the most mysterious particles in the universe. They’re strange, exotic bits of matter that are emitted by some nuclear reactions, and travel through space at nearly the speed of light. Trillions of them are created by the sun every second, and when they reach the Earth …

Sensors allow humans to feel and understand their world, and their development lays the foundation for the fulfillment of information society and has formed a huge industry. For its implementation the Internet of Things relies heavily on sensor technology.In the grand world of the “internet of things” (IoT), there are …

Graphene is a 1-atom-thick layer of tightly bonded carbon atoms arranged in a hexagonal lattice. Graphene the world’s first 2D nanomaterial, is widely regarded as the “wonder material” of the 21st century due to the combination of its extraordinary properties. As a single layer of graphite, it is the thinnest …

Nanoparticles have unique thermal, optical, physical, chemical, magnetic and electrical properties compared to their bulk material counterparts. These features can be exploited for next generation biosensors, electronics, catalysts and antimicrobials. Metallic nanoparticles are one important and widely studied group of materials, showing great diversity and many different uses   Over …

Ever-growing data generation driven by mobile devices, the cloud, the IoT , and big data, as well as novel AI applications, all part of the megatrends, requires continuous advancements in memory technologies.   RRAM is a nonvolatile memory that is similar to PCM. The technology concept is that a dielectric, …

A battery is an electrochemical device that stores electrical energy as chemical energy in its anode and cathode during the charging process, and when needed, releases the energy as electrical output during the discharge. An ideal battery is expected to have high specific energy, high power density, long cycle life, …

Today’s generation of body-armour systems can provide protection at various levels designed to defeat most common low- and medium-energy handgun rounds. However, currently the highest-threat-level ballistic needs in the market are fulfilled by special, high performance ceramics that tend to be very costly, fragile for standard handling, extremely heavy and …
