Innovative Perovskite Waveguides
Scientists from the University of Warsaw (UW) is Faculty of Physics in collaboration with other researchers from Poland as well as Italy, Iceland, and Australia, have demonstrated the creation of perovskite crystals with predefined shapes that can serve in nonlinear photonics as waveguides, couplers, splitters, and modulators. The research results were published in “Nature Materials”.
A Quantum Leap in Creating Exotic Materials
A Quantum Leap in Creating Exotic Materials
A study co-led by Nanyang Asst Prof Chang Guoqing of NTU’s School of Physical and Mathematical Sciences identified two types of van Hove singularities in the topological materials rhodium monosilicide (RhSi) and cobalt monosilicide (CoSi). They found that the van Hove singularities are near the Fermi level – the highest energy level that an electron can occupy at absolute zero temperature. In this situation, it is highly likely that the materials will exhibit desirable quantum properties, such as superconductivity and ferromagnetism.

Moving From the Visible to the Infrared: Developing High Quality Nanocrystals
In new research published in Nature Synthesis, University of Illinois at Urbana-Champaign bioengineering professor Andrew Smith and postdoctoral researcher Wonseok Lee have developed mercury selenide (HgSe) and mercury cadmium selenide (HgCdSe) nanocrystals that absorb and emit in the infrared, made from already well-developed, visible spectrum cadmium selenide (CdSe) precursors. The new nanocrystal products retained the desired properties of the parent CdSe nanocrystals, including size, shape and uniformity.

New Method for Determining the Exchange Energy of 2D Materials
Researchers from the University of Basel have looked at how the ferromagnetic properties of electrons in the two-dimensional semiconductor molybdenum disulfide can be better understood. They revealed a surprisingly simple way of measuring the energy needed to flip an electron spin.
CQT Scientists Achieve an Average Quantum Efficiency of 76.4% for the First Time Using a Single Photon Emitter Made From 2D Materials
Recently, an international team of researchers led by Singapore's CQT has come close with a single photon emitter made from two-dimensional materials and successfully suppressed non-radiative decay of localised exciton in these materials for the first time. In this study, researchers constructed the emitter using monolayer tungsten diselenide (WSe2), which is only one atom thick and generated excitons in excited states using lasers. As the exciton decays back to the ground state, it could randomly undergo either radiative or non-radiative decay.
