The growth mechanism of semiconductor nanowires (NWs) is still an argument of high interest, and it’s becoming clearer that simple pictures, such as the original vapour-liquid-solid model, fail to describe the complex behaviours observed under different growth conditions and for different materials.
Among the elemental diatomic molecules, O2 is the only one carrying a spin 1 magnetic moment. In the high pressure phases of oxygen the magnetic moment conspires with intermolecular forces to generate a rich phase diagram. Whereas, up to 80,000 atmospheres the moment persists, at pressures between 80,000 and 200,000 atmospheres, molecular magnetism apparently disappears, however with a number of unexplained vibrational and optical anomalies.
Herein is described a multidisciplinary approach to understand the performance limitations of small molecule organic light emitting transistors (OLETs) based on a layered architecture, an innovative architecture potentially competitive with the state of the art and more flexible for spectral emission control.
Using electric fields for magnetic writing is a very appealing opportunity, however, bulk multiferroic materials at room temperature have not been yet found. Instead, interfacial magnetoelectric coupling could be a viable path to achieve electrical writing of magnetic information in spintronic devices.
Here, we report on a room temperature ON-OFF electrical switching of the interfacial magnetization at the Fe/BaTiO3 interface.
