Illustration of boron arsenide crystal undergoing thermal energy transport
An illustration of a boron arsenide crystal, placed between two diamonds in a controlled chamber with thermal energy transported under extreme pressure. Research shows that when boron arsenide is subjected to extreme pressure, heat transfer slows down, contradicting conventional wisdom that heat always moves faster as pressure increases.
