http://www.learningaboutelectronics.com/Articles/How-to-calculate-alpha-of-a-transistor WebBJTs essentially behave as current amplifiers. A small base current is amplified to a larger current in the collector-emitter circuit resulting in a DC gain. This gain is referred to as Beta DC (βDC). Another important characteristic of BJTs is Alpha DC (αDC).
