Nyika itsva yeOptoelectronic zvishandiso

Vatsvagiri panhau-Israel Institute of Technology vakagadzira nzvimbo yakadzoraOptical laserzvichibva pane imwe tomic layer. Kuwanikwa uku kwacho kwakaitwa nekubatana kwespin-decraction pakati peimwe atomic layer uye yakamanikidzwa phomoni.
Mhedzisiro, yakaburitswa mumidziyo yemasikirwo uye yakarongedzwa mukutsvagurudza kwayo pfupi, inovhara nzira yekudzidza kweiyo yakabatana spin-inoenderana ne phenomena mune clenomena mune clenomena mune clenomena mune clenomena mune yekare uyeQuantum Systems, uye anovhura mavhenekets idzva ekutsvaga kwakakosha uye mashandisiro eElectron uye Photon Spin muOptoelectronic zvishandiso. Iyo Spin Optic Sosi inosanganisa iyo Photon mode neElectron Shanduko, iyo inopa nzira yekufunda iyo spin ruzivo rwechinguvana pakati peaine magetsi uye nekuvandudza midziyo yepamberi optoelfronic.

Spin Valley Optical microcaviles yakavakwa nekudyidzana photonic spin latthices ine inversion asymmetry (yero core dunhu) uye inversion symmetry (yecymmetry).
Kuti uvake izvi zvinyorwa, prerequisite ndeyekubvisa iyo spin degenerance pakati pemaviri akapesana spin nyika mu Photon kana elekron chikamu. Izvi zvinowanzoitika nekushandisa munda wemagineti pasi peFareday kana zeman maitiro, kunyangwe nzira idzi dzinowanzoda nzvimbo yakasimba yemagineti uye haigoni kuburitsa microource. Imwe nzira yekuvimbisa yakavakirwa pane geometric kamera system iyo inoshandisa gadziriso yemagineti yemagineti yekugadzira iyo spin-inopatsanura nyika yemifananidzo mune mwaka wepakati.
Zvinosuruvarisa kuti zvopfuura zveSpin Sprit nyika dzakavimbisa zvakanyanya pane yakaderera-masasi Factor nzira, iyo inosimbisa matambudziko ekupokana neyekuchengetera uye shanduko yezvinhu. Iyi nzira inovhiringidzwa zvakare neiyo spin-inodzorwa-inodzora chimiro cheBlocky laser-kuwana zvinhu, izvo zvisingakwanise kushandiswa kana kuti hazvishandiswe nyore kudzoraZvigadzirwa zvechiedza, kunyanya mukushaikwa kwemagineti emagineti pamhepo tembiricha.
Kuti uwane yakakwirira-q spin-kupaza nyika, vaongorori vakavaka Photonic Spin Latthices neSymmetric envelopu yakabatanidzwa neAWS2 Single Layer, kugadzira yakazotambudza mipata yeSpin. Iyo yekutanga inverse asymmetric lattice inoshandiswa nevaongorori vane zvinhu zviviri zvakakosha.
Iyo inotorwa inoshatiswa Idzi vekoti dzinoputira iyo spin degradation bhandi mumatavi maviri akaparadzaniswa mune mwaka wekunakidzwa nzvimbo, inozivikanwa se photonic slumberg mhedzisiro.
Vaviri vakakwira
Muzvinafundo Koren akacherekedza: Zvakananga, avo ± kOptical Source.
Mune imwe-danda rakabatanidzwa spin Vallecavity, iyo ± k Panguva imwe chete, iyolaserMechanism inotyaira chikamu chekutanga-yakazvimirira
Covery Cohence anofambiswa neiyi laser mechanism inobvisa kudiwa kwekudziya kwekudziya kwekuparadza kwemukati kupararira. Uye zvakare, iyo shoma kurasikirwa mamiriro eRashba monolayer laser inogona kuunganidzwa neiyo mutsara (kutenderera) pombization, iyo inopa nzira yekudzora laser uye yekubatana kwemhepo. "
Muzvinafundo Hasman anotsanangura kuti: "ChakaratidzwaPhotonicSpin Valley Rashaces inopa iyo general mechanism yekuvaka pasi-inoburitsa spin opt zvinyorwa. Colley Cohence yakaratidza mune imwe-deya yakabatanidzwa spin Valleycavity inounza nhanho imwe padyo nekuita kuti uwane ruzivo rwehuwandu pakati pe ± k 'Valley inonakidza kuburikidza nejimiti.
Kwenguva yakareba, timu yedu yave ichikura spin optcs, uchishandisa Photon Spin sechishandiso chinoshanda chekudzora maitiro eyemafungo yemagetsi. Muna 2018, kushushikana neMupata Pseudo-spin muzvisikwa zviviri, takatanga chirongwa chenguva refu kuti tiongorore basa rekutora kweatomu Isu tinoshandisa iyo isiri-yemuno berry chikamu chakaremara kugadzirisa kugadzirisa dambudziko rekuwana cohenting geometric phase kubva kune imwechete yeMupata Uptiton.
Nekudaro, nekuda kwekushayikwa kwekusimba kwakasimba pakati pemanyoro pakati penyaya, huwandu hwenhunghe hwakaenzana hwemitezo yemupata muRashuba sosi yakawanikwa isipo Dambudziko iri rinotikurudzira kuti tifunge nezveRashuba Model yeakakwirira q q q q Mushure mekusimudzira nzira nyowani dzemuviri, isu takaita iyo Rashsa imwechete-layer Laser inotsanangurwa mupepa iri.

Kubudirira uku kunovhara nzira yekudzidza kweCheent Spin Correlation muClenomena muClenomena Kuongorora uye huwandu hwenguva, uye inovhura nzira itsva yekutsvaga uye yekushandisa yeSpintronic uye photonic Optoectronic zvishandiso.
