How match is madeAntimony trisulfide cannot be ignited by the heat of friction, even in the presence of an oxidizing agent like potassium chlorate, and it requires another source of ignition to start the combustion. That source of ignition comes from the striking surface, which is deposited on the side of the matchbox or on the back cover of the matchbook.
Doping in SemiconductorsWhen an impurity is added to silicon or germanium without modifying the crystal structure, an Ntype material is produced. In some atoms, electrons have five electrons in their valence band such as arsenic (As) and antimony (Sb). Doping of silicon with either impurity must not change the crystal structure or the bonding process.
