Sandwich structure of nanocrystals as quantum light source

Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create ...

Chirality and chiral-induced spin selectivity

Chirality describes a molecule that can't be superimposed on its own mirror image. Two geometrically different chiral molecules of the same formula, distinguished by the R- and S- configuration, exhibit different optical ...

Simple technique ushers in long-sought class of semiconductors

Breakthroughs in modern microelectronics depend on understanding and manipulating the movement of electrons in metal. Reducing the thickness of metal sheets to the order of nanometers can enable exquisite control over how ...

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, ...

Interfaces are key in metal oxide superlattices

(Phys.org)—Materials called transition metal oxides have physicists intrigued by their potentially useful properties—from magnetoresistance (the reason a hard drive can write memory) to superconductivity.

New superlattice material for future energy efficient devices

A team of international physicists including Jennifer Cano, Ph.D., of Stony Brook University, has created a new material layered by two structures, forming a superlattice, that at a high temperature is a super-efficient insulator ...
