The control of magnetization by low power approaches, instead of power-hungry magnetic fields generated by electric currents, is a key challenge for future spintronics devices. Researchers have now shown that by exploiting magnetoelastic coupling, magnetization can be accurately controlled in nanostructures.

The development of quantum computers relies on storing and transferring entangled states, and quantum dots are a promising platform for both. In this work, it is shown that energy differences between exciton eigenstates below 1 micro-electron-volt can be achieved by simultaneously applying electric and magnetic fields to a semiconductor quantum dot.

Despite progress that has been made over the past decade, fundamental understanding of carrier injection and extraction mechanisms in organic solar cells is lacking. In this paper, the distinct processes that drive charge transfer in organic bulk heterojunction solar cells are identified, and importantly, a method of distinguishing between them is proposed.

Future quantum computing devices are expected to rely on the detection of multiple individual trapped ions. In recent work, scientists have used a fiber-optic coupled array of diffraction lenses to discriminate the fluorescence of individual Ca ions. Their array is scaleable and achieves efficiencies of nearly 0.4% at detection times of under 200 microseconds.

The problem of achieving p-type doping in ZnO is of paramount importance for the realization of ZnO-based optoelectronic devices. First-principles simulations show that doping with Group V elements is unlikely to provide a solution, due to deep transition energies and donor compensation.
