Highly strained Ge micro-blocks bonded on Si platform for Mid-Infrared photonic applications
Alban Gassenq, Kevin Guilloy, Nicolas Pauc +7
Adding sufficient tensile strain to Ge can turn the material to a direct bandgap group IV semiconductor emitting in the mid-infrared wavelength range. However, highly strained-Ge c…
