Phys.org October 16, 2023 Ferroelectrics possess a spontaneous polarization that is switchable by an electric field and is critical for the development of low energy nanoelectronics and neuromorphic applications. However, the realization of switchable polarization in metal oxides with simpler structures has been a major challenge. An international team of researchers (Australia, India) demonstrated the presence of robust switchable polarization at the level of a single nanocrystalline in magnesium-doped zinc oxide thin films with polar wurtzite crystal structures. Voltage control of the polarization and the coupled electronic transport behavior revealed a giant resistance change of approximately 10000% . Time- and […]

The way of water: Making advanced electronics with H2O
Science Daily May 16, 2022 The next generation of photovoltaics, semiconductors and LEDs could be made using perovskites. The presence of moisture can lead to defects in the materials, causing them to fall apart more quickly when they’re being used in a device. Researchers in Australia found a simple way to control the growth of phase-pure perovskite crystals by harnessing water as a positive factor by changing the ratio of water to solvent during the early stages of the process, they could choose to grow different types of perovskite crystals, with structures to suit various purposes. They identified that the […]
Electronics of the future: A new energy-efficient mechanism using the Rashba effect
Science Daily December 27, 2018 Researchers in Japan using the Rashba effect for generating spin currents in material structures that possess electrons with desirable spin properties. They developed a mechanism to generate a spin current without energy loss from a series of simulations for new quasi-1D materials based on bismuth-adsorbed indium that exhibit a giant Rashba effect. This mechanism does not require an external magnetic field to generate nondissipative spin current. The process would simplify potential spintronic devices and would allow for further miniaturization… read more. Open Access TECHNICAL ARTICLE
