Electronics Devices and Circuit Theory 10th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla 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.

Electronics Devices and Circuit Theory 10th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla 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 n- type material. The result is a p-n junction.

Electronics Devices and Circuit Theory 10th 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 10th Edition - Boylestad Electronics Fundamentals 8 th edition - Floyd/Buchla p-n Junction

Electronics Devices and Circuit Theory 10th 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 10th 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 10th 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 10th 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 10th 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 10th 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.
