Majority and Minority Carriers Majority Carriers – The majority carriers in n-type materials are electrons. – The majority carriers in p-type materials are holes. • Minority Carriers – The minority carriers in n-type materials are holes. – The minority carriers in p-type materials are electrons.

p-n Junctions • One end of a silicon or germanium crystal can be doped as a p-type material and the other end as an ntype material. • The result is a p-n junction. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
p-n Junction The result is the formation of a depletion region around the junction. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla

Diodes The diode is a 2 -terminal device. A diode ideally conducts in only one direction. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions A diode has three operating conditions: – No bias – Forward bias – Reverse bias Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions • No Bias – No external voltage is applied: VD = 0 V – No current is flowing: ID = 0 A – Only a modest depletion region exists Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions • Reverse Bias – External voltage is applied across the p-n junction in the opposite polarity of the p- and n-type materials. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions • Reverse Bias The reverse voltage causes the depletion region to widen. The electrons in the n-type material are attracted toward the positive terminal of the voltage source. The holes in the p-type material are attracted toward the negative terminal of the voltage source. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions • Forward Bias – External voltage is applied across the p-n junction in the same polarity as the p- and n-type materials. Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
Diode Operating Conditions • Forward Bias Electronics Devices and Circuit Theory 10 th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla
