Coleman was among the first to demonstrate the effectiveness of the process known as metalorganic chemical vapor deposition to make lasers, solar cells and photodetectors with better performance characteristics. This method is widely used in photonics technologies, which combine the physics of light with electricity. The technology helps transmit the information that is communicated through cellphones, desktop Internet connections and medical equipment.
His work has led to wider application and manufacture of semiconductor lasers. His research has refined not only semiconductor devices, but also the materials used to make them.
