Antimatter is exactly what you might think it is -- the opposite of normal matter, of which the majority of our universe is made. These anti-particles are, literally, mirror images of normal matter. Each anti-particle has the same mass as its corresponding particle, but the electrical charges are reversed.. bandgap. energy illuminates a negative electron affinity (NEA) .
