ATTOSECond Pulsesguhishura amabanga yigihe cyo gutinda
Abahanga muri Amerika, babifashijwemo na Attosecond Plise, bagaragaje amakuru mashya yerekeyeIngaruka ya Phofeterictric: theAmafoto ya PhofeterictricGutinda bigera kuri 700 atton, birebire kuruta mbere. Izi mbogamizi zigezweho zubushakashatsi zisanzwe zirimo gusobanukirwa imikoranire yimbitse hagati ya electron, biganisha ku iterambere ryikoranabuhanga nka semicondu.
Ingaruka ya Phofeterictric bivuga ko iyo urumuri rumurikira molekile cyangwa atom hejuru yicyuma, fores ikorana na molekile cyangwa atom kandi irekura electron. Iyi ngaruka ntabwo arimwe gusa murufatiro rwingenzi rwamanishi rwamafaranga, ariko kandi rufite ingaruka zikomeye kuri fiziki zigezweho, chimie nibikoresho siyanse. Ariko, muriki gice, icyahatiye gutinda igihe cyabaye ingingo itavugwaho rumwe, kandi icyitegererezo zitandukanye cyatusobanuye cyabisobanuye muburyo butandukanye, ariko nta bwumvikane buhujwe bwashizweho.
Nkuko urwego rwa siyanse yatangaje rwateye imbere mu buryo bukomeye mu myaka yashize, iki gikoresho kigaragara gitanga uburyo butigeze bubaho gushakishwa Microscopique. Mu gupima neza ibyabaye bibaho mugihe gito cyane, abashakashatsi bashoboye kugira amakuru menshi kubyerekeye imyitwarire ishimishije yibice. Mu bushakashatsi buherutse, bakoresheje urukurikirane rw'ibikomeye-ubukana bwa X-Ray Pulses Inkomoko y'umucyo ku kigo cya kabiri cya STAnford.
Kugirango ukomeze gusesengura inzira za electron yasohotse, bakoresheje kugiti cyaboLaser Pulsesgupima ibihe byo kuryama bya electron muburyo butandukanye. Ubu buryo bwabemereye kubara neza itandukaniro rikomeye hagati y'ibihe bitandukanye biterwa n'imikoranire iri hagati ya electron, yemeza ko gutinda bishobora kugera kuri atton 700. Birakwiye ko tumenya ko ubu buvumburwa butere rwemeza gusa ibitekerezo bimwe byabanje, ahubwo binatera ibibazo bishya, bigatuma ibitekerezo bifatika bigomba kongera gusuzumwa no kuvugururwa.
Byongeye kandi, ubushakashatsi bwerekana akamaro ko gupima no gusobanura ibi byatinze, bikaba bimeze nabi kugirango dusobanukirwe ibisubizo bigeragejwe. Muri Eretin Crystallography, Gutekereza kwa Ubuvuzi, nibindi bikorwa byingenzi birimo imikoranire ya X-ray ifite akamaro, aya makuru azaba ashingiye ku buryo bwingenzi bwo guhitamo uburyo bwa tekiniki no kunoza ubuziranenge. Kubwibyo, itsinda ryateganya gukomeza gushakisha imbaraga za elegitoronike yubwoko butandukanye bwa molekile muburyo bwa elegitoronike muburyo bwa elegitoronike muburyo bukomeye bwo guteza imbere ikoranabuhanga rifitanye isano mugihe kizaza.
