Silicon LED/ laser integration into standard electronic circuits powered by same battery or power supply that runs rest of chip

"can't build all-silicon lasers/ efficient LEDs due to silicon's indirect band gap; for electron in silicon energy level drop/ emit light needs momentum change, but photons carry almost 0 momentum, overcome decorating bulk silicon with ultrasmall copper particles/ confining light to <2 nm space increasing momentum distribution until matches that required by silicon’s electrons, converting silicon into direct band gap material allowing 100,000X increased light emission intensity without needing phonons"
