Lefatše la lisebelisoa tsa elektroniki le itšetlehile ka libapali tse fapaneng, e 'ngoe le e 'ngoe e bapala karolo ea bohlokoa. Har'a tsena, li-diode li hlahella ka matla a tsona a ho laola phallo ea motlakase. Kajeno, re hlahloba mofuta o itseng - diode ea Schottky, motsoako o ikhethang oa tšepe le semiconductor e nang le mefuta e mengata ea lisebelisoa tsa bohlokoa.
Ho utloisisa Schottky Diode
Ho fapana le diode e tloaelehileng ea pn junction, diode ea Schottky e theha mateano pakeng tsa tšepe le semiconductor. Sena se theha mokoallo oa Schottky, sebaka seo ho phalla ha elektronike ho thibetsoeng. Ha motlakase o sebelisoa ka tsela ea pele (e ntle ka lehlakoreng la tšepe), li-electrone li hlōla mokoallo 'me hona joale ho phalla habonolo. Leha ho le joalo, ho sebelisa motlakase oa reverse ho baka tšitiso e matla, ho sitisa phallo ea hona joale.
Letšoao le Litšobotsi
Letšoao la Schottky diode le tšoana le diode e tloaelehileng e nang le mola o tšekaletseng o arolang khutlotharo e 'ngoe e lebileng ho theminale e nepahetseng. Mokokotlo oa eona oa VI o ts'oana le pn junction diode, empa ka phapang ea bohlokoa: ho theoha ho tlase haholo ho ea pele, hangata lipakeng tsa 0.2 ho isa ho 0.3 volts. Sena se bolela ho theola tahlehelo ea matla nakong ea ts'ebetso.
Molao-motheo o Sebetsang
Molao-motheo oa ts'ebetso ea Schottky diode ke matla a fapaneng a ka bang teng a lielektrone ka thepa e fapaneng. Ha tšepe le semiconductor ea mofuta oa n li kopana, lielektrone li phalla ho pholletsa le mateano ka mahlakoreng ka bobeli. Ho sebelisa motlakase o eang pele ho matlafatsa phallo ho ea ho semiconductor, ho nolofalletsang hona joale.
Lisebelisoa tsa Schottky Diode
Li-diode tsa Schottky li iphumana li le lits'ebetsong tse fapaneng tsa elektroniki ka lebaka la thepa ea tsona e ikhethang:
RF Mixers and Detectors: Lebelo la tsona le ikhethang la ho chencha le bokhoni ba maqhubu a phahameng li li etsa hore li tšoanelehe bakeng sa lits'ebetso tsa radio frequency (RF) joalo ka li-ring ring mixer.
Li-Rectifiers tsa Matla: Bokhoni ba ho sebetsana le maqhubu a phahameng le li-voltage ka ho theoha ha motlakase o eang pele o li etsa hore e be li-rectifiers tse sebetsang hantle, tse fokotsang tahlehelo ea matla ha e bapisoa le diode tsa pn junction.
Matla KAPA Lipotoloho: Lipotolohong moo lisebelisoa tse peli tsa motlakase li tsamaisang mojaro (joaloka li-backups tsa betri), li-diode tsa Schottky li thibela hore hona joale ho se ke ha khutlela phepelong e le 'ngoe ho tloha ho e' ngoe.
Lisebelisoa tsa Solar Cell: Liphanele tsa letsatsi hangata li hokahantsoe le libeteri tse nchafatsoang, hangata li-lead-acid. Ho thibela hona joale ho phalla ho khutlela liseleng tsa letsatsi bosiu, li-diode tsa Schottky li sebelisoa ka mokhoa oa ho pota-pota.
Melemo le Mefokolo
Schottky diode e fana ka melemo e mengata:
Matla a Tlase: Sebaka sa ho fokotseha se sa tsotelleng se fella ka matla a tlase, se etsang hore se tšoanelehe bakeng sa lits'ebetso tse phahameng haholo.
Ho Fetola ka Potlako: Phetoho e potlakileng ho tloha ho ea pele ho ea linaheng e lumella ts'ebetso ea lebelo le phahameng.
High Current Density: Sebaka se senyenyane sa ho fokotseha se ba nolofalletsa ho sebetsana le maemo a phahameng a hona joale.
Low Turn-On Voltage: Ho theoha ha motlakase oa pele ho 0.2 ho isa ho 0.3 volts ho tlase haholo ho feta pn junction diode.
Leha ho le joalo, ho na le drawback e le 'ngoe ea bohlokoa:
High Reverse Leakage Hajoale: Li-schottky diode li bonts'a ho lutla ha morao ha morao ha ho bapisoa le diode tsa pn junction. Sena e ka ba ho tšoenyeha lits'ebetsong tse itseng.
Qetello
Schottky diode, e nang le mateano a eona a ikhethang a tšepe-semiconductor, e fana ka motsoako oa bohlokoa oa ho theoha ha motlakase o tlase, lebelo la ho fetoha ka potlako, le bokhoni bo phahameng ba ho sebetsana le hona joale. Sena se etsa hore e be likarolo tse ke keng tsa nkeloa sebaka lipotolohong tse fapaneng tsa elektroniki, ho tloha phepelong ea motlakase ho isa litsing tsa matla a letsatsi. Ha theknoloji e ntse e tsoela pele ho fetoha, Schottky diode e na le bonnete ba hore e tla lula e le mosebetsi o ka tšeptjoang indastering ea lisebelisoa tsa elektroniki.
