Recent manipulations of excitons in moiré superlattices
Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, they stay bound together,.....»»
On-surface synthesis of graphene molecules and their superlattices
NUS scientists have devised a new method for the synthesis of nanographene molecules with a high product yield for the development of next generation quantum devices......»»
Dual character of excitons in the ultrafast regime: Atomic-like or solid-like?
Excitons are quasiparticles which can transport energy through solid substances. This makes them important for the development of future materials and devices—but more research is needed to understand their fundamental behavior and how to manipulat.....»»
Moiré patterns facilitate discovery of novel insulating phases
Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can suppress electrical conduc.....»»
Terbium (III)-doped fluorescent glass for biomedical research
Optical investigations and manipulations often form the core of biological experiments. In a new report now published in Science Advances, Kazuki Okamato and a team of scientists in pharmaceutical sciences, neuroscience, medicine, physics and artific.....»»
