HSIC Group Revises Kirchoff’s Law

After discovering a flaw in the 160-year-old circuit theory, Han Wui Then’s Transistor Laser research has revised Kirchoff’s current law to account for optical generation/recombination. His research enables a simple and intuitive way to view the relationship between electrons and photons in direct semiconductors.
