Study reveals potential of superparaelectric materials as gate dielectrics in next-gen microelectronics

In our communication-centered society, Moore’s law sets a high expectation for the increasing rate of the packing density of Si-based transistors. This drives the search for thickness-scalable high dielectric constant (high k) gate layers. Current material candidates, from simple binary oxides to complex polar oxides, all have failed to solve the “polarizability-scalability-insulation robustness” trilemma, hence…

Catalina’s invasive mule deer are spared death from above: They still face an uncertain fate

Santa Catalina Island’s evasive mule deer dodged a bullet—or several—May 29. At a special meeting of the Los Angeles County Fish and Wildlife Commission, the Catalina Island Conservancy, which controls 88% of the island, announced it was scrapping plans to eradicate the nonnative species by shooting them from helicopters with high-powered rifles. Santa Catalina Island’s evasive…

Astronomers explore the properties of a peculiar stellar stream

Using ESA’s Gaia satellite and the MMT Observatory, astronomers have investigated a peculiar stream of stars in our galaxy named Theia 456. Results of the study, published May 21 on the pre-print server arXiv, deliver important insights into the properties and origin of this stellar stream. Using ESA’s Gaia satellite and the MMT Observatory, astronomers have…
