New Laser for Computer Chips

New Laser for Computer Chips

Scientists from Forschungszentrum Jülich and the Paul Scherrer Institute in Switzerland in cooperation with international partners have presented the first semiconductor consisting solely of elements of main group IV. As a consequence, the germanium-tin (GeSn) laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer [...]

Lens-Free Microscope Detects Cancer at Cell Level

Lens-Free Microscope Detects Cancer at Cell Level

UCLA researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.   The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. [...]

Scientists Measure Speedy Electrons in Silicon

Scientists Measure Speedy Electrons in Silicon

The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our age.   An international team of physicists and chemists based [...]
