مكشاف شبه الموصلات: الفرق بين النسختين

Most silicon [[Elementary particle|particle]] detectors work, in principle, by [[Doping (semiconductor)|doping]] narrow (usually around 100 micrometers wide) strips of [[silicon]] to make them into [[diode]]s, which are then [[p-n junction#Reverse bias|reverse biased]]. As charged particles pass through these strips, they cause small ionization currents which can be detected and measured. Arranging thousands of these detectors around a collision point in a [[particle accelerator]] can give an accurate picture of what paths particles take. Silicon detectors have a much higher resolution in tracking charged particles than older technologies such as [[cloud chamber]]s or [[wire chamber]]s. The drawback is that silicon detectors are much more expensive than these older technologies and require sophisticated cooling to reduce leakage currents (noise source) as well as suffer degradation over time from [[radiation]].▼
