Dziko lazinthu zamagetsi limadalira anthu osiyanasiyana, aliyense akugwira ntchito yofunikira. Mwa izi, ma diode amawonekera chifukwa cha kuthekera kwawo kuwongolera kayendedwe ka magetsi. Masiku ano, timayang'ana mumtundu wina - diode ya Schottky, kuphatikiza kwapadera kwachitsulo ndi semiconductor ndi ntchito zosiyanasiyana zamtengo wapatali.
Kumvetsetsa Schottky Diode
Mosiyana ndi diode yodziwika bwino ya pn junction, diode ya Schottky imapanga mphambano pakati pa chitsulo ndi semiconductor. Izi zimapanga chotchinga cha Schottky, chigawo chomwe ma electron amayendera. Pamene magetsi akugwiritsidwa ntchito kutsogolo (zabwino kumbali yachitsulo), ma elekitironi amagonjetsa chotchingacho ndipo panopa akuyenda mosavuta. Komabe, kugwiritsa ntchito reverse voteji kumapanga chotchinga champhamvu, ndikulepheretsa kuyenda kwapano.
Zizindikiro ndi Makhalidwe
Chizindikiro cha diode ya Schottky chimafanana ndi diode yokhazikika yokhala ndi mzere wopingasa womwe ukuloza makona atatu kuloza kutheminali yabwino. Mapiritsi ake a VI ndi ofanana ndi diode ya pn junction, koma ndi kusiyana kwakukulu: kutsika kwambiri kutsogolo kwamagetsi, makamaka pakati pa 0.2 mpaka 0.3 volts. Izi zimatanthawuza kuchepetsa kutaya mphamvu panthawi yogwira ntchito.
Mfundo Yogwira Ntchito
Mfundo yofunika kwambiri yogwiritsira ntchito Schottky diode yagona mu mphamvu zosiyanasiyana za ma elekitironi muzinthu zosiyanasiyana. Chitsulo ndi semiconductor yamtundu wa n zikakumana, ma elekitironi amayenda kudutsa mbali zonse ziwiri. Kuyika voteji yakutsogolo kumalimbitsa kuyenderera kwa semiconductor, ndikupangitsa kuti pakhale pano.
Kugwiritsa ntchito kwa Schottky Diode
Schottky diode amapezeka muzinthu zosiyanasiyana zamagetsi chifukwa cha mawonekedwe awo apadera:
RF Mixers and Detectors: Kuthamanga kwawo kwapadera komanso kuthamanga kwafupipafupi kumawapangitsa kukhala abwino kwa ma radio frequency (RF) ngati zosakaniza mphete za diode.
Zowongolera Mphamvu: Kutha kuthana ndi mafunde akulu ndi ma voltages ndi kutsika kwamagetsi otsika kumawapangitsa kukhala owongolera bwino mphamvu, kuchepetsa kutayika kwa mphamvu poyerekeza ndi ma pn junction diode.
Mphamvu KAPENA Mazungulira: M'mabwalo omwe magetsi awiri amayendetsa katundu (monga zosungira batri), ma diode a Schottky amalepheretsa kuti pakali pano zisabwererenso ku gawo limodzi kuchokera kwina.
Kugwiritsa Ntchito Ma cell a Dzuwa: Ma solar panel nthawi zambiri amalumikizidwa ndi mabatire omwe amatha kuchajwanso, omwe nthawi zambiri amakhala ndi asidi wa lead. Pofuna kupewa kuti madzi asabwererenso m'maselo a dzuwa usiku, ma Schottky diode amagwiritsidwa ntchito podutsa.
Ubwino ndi Kuipa kwake
Schottky diode amapereka zabwino zingapo:
Low Capacitance: Chigawo chochepa chochepa chimapangitsa kuti chikhale chochepa, chomwe chimawapangitsa kukhala oyenera kugwiritsa ntchito maulendo apamwamba.
Kusintha Kwachangu: Kusintha kofulumira kuchokera kumayiko kupita kumayiko ena kumalola kuti pakhale ntchito yothamanga kwambiri.
Kuchuluka Kwambiri Pakalipano: Dera laling'ono lochepetsera limawathandiza kuti athe kuthana ndi zovuta zamakono.
Low Turn-On Voltage: Kutsika kwamagetsi kutsogolo kwa 0.2 mpaka 0.3 volts ndikotsika kwambiri kuposa ma pn junction diode.
Komabe, pali drawback imodzi yofunika:
Kutayikira Kwambiri Pakalipano: Ma diode a Schottky amawonetsa kutayikira kwapang'onopang'ono poyerekeza ndi ma pn junction diode. Izi zitha kukhala zodetsa nkhawa pazinthu zina.
Mapeto
Diode ya Schottky, yokhala ndi zitsulo zapadera zachitsulo-semiconductor, imapereka kuphatikiza kwamtengo wapatali kwa kutsika kwamagetsi otsika, kuthamanga kwachangu, ndi mphamvu zamakono zogwirira ntchito. Izi zimawapangitsa kukhala zigawo zosasinthika m'mabwalo osiyanasiyana amagetsi, kuchokera kumagetsi kupita kumagetsi a dzuwa. Pamene teknoloji ikupitirizabe kusinthika, diode ya Schottky idzakhalabe yodalirika pamakampani opanga zamagetsi.
