Strange new twist: Researchers discover Moebius symmetry in metamaterials

For years, scientists have been searching for an example of Moebius symmetry in natural materials without any success. Now a team of scientists has discovered Moebius symmetry in metamaterials - materials engineered from artificial 'atoms' and 'molecules' with electromagnetic properties that arise from their structure rather than their chemical composition.

Muscle filaments make mechanical strain visible

Plastics-based materials have been in use for decades. But manufacturers are facing a serious hurdle in their quest for new developments: Substantial influences of the microscopic material structure on mechanical material properties cannot be observed directly. The synthetic polymer molecules are simply too small for microscopic observation in mechanical experiments. A team of physicists has now developed a method that allows just these kinds of measurements.

High-quality III-V layers on Si(001) pave the way to high-performance Ge/III-V CMOS

Imec has demonstrated the selective area growth of high-quality InP layers on 200mm Si(001) wafers. Key to avoiding the typically formed and unwanted antiphase boundaries (APBs) is the creation of atomic steps on a thin Ge buffer layer. This result is a major step forward towards the fabrication of high-performance Ge/III-V CMOS devices and the integration of optoelectronic devices on a Si chip.
