A gold butterfly can make its own semiconductor skin

Science Daily  February 6, 2020 Current methods for placing nano-sized semiconductors on metallic particles to utilize them in nano-lasing and nano-lithography lack precision or are too costly. Researchers in Japan have developed a method based on a hydrothermal synthesis reaction to locally and selectively synthesize zinc oxide in a plasmonic nanoantenna. They first made evident the role of localized surface plasmon resonances (LSPR) for achieving efficient heating of gold nanostructures. Then, by selectively addressing one of the LSPRs of a gold antenna, they demonstrated that localized zinc oxide formation at the targeted location of the antenna can be achieved due […]

Chipmakers Test Ferroelectrics as a Route to Ultralow-Power Chips

IEEE Spectrum  February 26, 2018 Researchers at a company in the US chose a ferroelectric material that does not require ions or atoms to relocate which slows things down in ferroelectric materials. In their experimental 14-nm transistors, clouds of electrons around silicon-doped hafnium dioxide experience the polarization. Ring oscillators made with these transistors can switch at the same frequency as those made with the usual recipe, yet they require just 54 mV to achieve a tenfold increase in the current. Their devices require a 3- to 8-nm-thick layer of ferroelectric material, which is still relatively thick… read more. Related TECHNICAL […]

New center to develop next-generation computing technologies

Nanowerk  January 15, 2018 Applications and Systems-driven Center for Energy-Efficient integrated Nano Technologies (ASCENT) led by the University of Notre Dame will pursue four areas of technology including three-dimensional integration of device technologies beyond a single planar layer (vertical CMOS); spin-based device concepts that combine processing and memory functions (beyond CMOS); heterogeneous integration of functionally diverse nano-components into integrated microsystems (heterogeneous integration fabric); and hardware accelerators for data intensive cognitive workloads (merged logic-memory fabric). ASCENT is funded by Semiconductor Research Corporation… read more.
