Osaka University researchers prepared 2D layered, visible-light-absorbing bismuth sulfide semiconductors using a two-step process. The resulting film exhibited morphology that supported excellent semiconductor performance. The simplicity and versatility of the processing method, which uses non-toxic, abundant materials, makes bismuth sulfide a viable alternative to commercially available photoresponsive devices.
Osaka University researchers developed the first device that can detect single-electron events in a self-assembled quantum dot in real time. The device detects the single-electron tunneling events of one quantum dot as changes in the current produced by a second quantum dot in close proximity. This device allows single-electron events in quantum dots to be investigated, which is beneficial for the development of photonic devices and quantum computing.
In research that may help bridge the divide between the nano and the macro, Brown University chemists have used pyramid-shaped nanoparticles to create what might be the most complex macroscale superstructure ever assembled.
Fundamental research: FLEET study of ultracold atomic gases at Swinburne University of Technology finds quantum anomaly, strongly interacting particles breaking classical symmetry in a 2D Fermi gas. Out today in Physical Review Letters.
An international team of researchers, affiliated with UNIST has presented an innovative wearable technology that will turn your skin into a loudspeaker.
The University of Tokyo Institute of Industrial Science researchers have created a model to explore the transition behavior of crystal lattices. Their system, based on spheroid particles with a permanent dipole, showed that the combination of anisotropic steric and dipole effects causes frustration that induces the coupling between polarization and strain, resulting in the self-organization. These findings are expected to contribute to the rational design of materials for applications including electro-mechanical actuators and electro-caloric refrigerators.
Sandwiching two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases and an ultrathin layer of aluminum oxide can significantly reduce the risk of component failure due to overheating, according to a new study published in the journal of Advanced Materials led by researchers at the University of Illinois at Chicago College of Engineering.
SUTD researchers have discovered a one-size-fits-all master equation that shall pave the way towards better design of 2D material electronics.
Scientists have developed a photoelectrode that can harvest 85 percent of visible light in a 30 nanometers-thin semiconductor layer between gold layers, converting light energy 11 times more efficiently than previous methods.
An international research group improved perovskite solar cells efficiency by using materials with better light absorption properties. For the first time, researchers used silicon nanoparticles. Such nanoparticles can trap light of a broad range of wavelengths near the cell active layer. The particles themselves don't absorb light and don't interact with other elements of the battery, thus maintaining its stability. The research was published in Advanced Optical Materials.
