The goal is to develop a range of areas where they can make improvements, such as new levels of control of semiconductorproperties on a near-atomic level to light mixing and heat management.
Researchers at the University of Toronto used everyday Scotch Tape (or double-sided poster tape, specifically) to bestow a semiconductor with superconducting properties.
The colour depends on the properties of the semiconductor, and these can be tuned to produce light that is similar to natural daylight but with virtually no ultraviolet or heat.
By carefully controlling its properties, he could turn a single chip of semiconductor into resistors, capacitors and transistors connected in any way he liked.
