spin transister

chumbak roop seey samvedansheel transister (jise spin transister yaa spintronic transister key roop mein bhee jaanaa jaataa haye-jise spintronics key liye naamit kiya gayaa haye, vaha takneek jise yeh vikas huaa thaa), mool roop seey 1990 mein supriya datt aur vishwajit daas dwara prastaavit kiya gayaa thaa, joe vartamaan mein abhee bhee vikasit kiya jaa rhaa haye, 1940 key dashak mein aavishkaar kiye gaye samanya transister parr ack behtar design haye. spin transister swabhavik roop seey dou (aur kewal dou) spin sthitiyon mein seey ack koo pradarshit karane key liye electrons (aur anya fermian) kii kshamata parr shodh key parinamswarup aataa haih jise "spin upp" aur "spin down" key roop mein jaanaa jaataa haye. iss prakaar, spin transister dou-avastha quantum pranali koo moort roop dene key roop mein electron spin parr kaam karate hain. apane poorvavarti key vipareet, joe ack vidyut dhaara parr kaam kartaa haye, spin transister adhik maulik star parr electrons parr kaam karate hain; yeh anivarya roop seey jaankaari koo sangraheet karane key liye spin kii vishesh sthitiyon mein sett kiye gaye electrons kaa anuprayog haye.
niyamit transister kii tulanaa mein ack laabh yeh haye kii inn spin avasthaon kaa pataa lagaaya jaa sakata haye aur binaa kissy vidyut pravaah key anuprayog kii aavashyakta key parivartit kiya jaa sakata haye. yeh pataa lagaane vaale hardware (jaise haard drive haid) key liye anumati detaa haye joe aaj key upkaranon kii tulanaa mein bahut chhote lekin aur bhee adhik samvedansheel hain, joe aaj key detta bhandaran upkaranon parr upayog kiye jaane vaale minut shulk kaa pataa lagaane key liye shore emplifiers parr bharosa karate hain. sambhaavit antim parinam aise upkaran hain joe cumm jagah mein adhik detta sangraheet curr sakate hain aur cumm mahangi samagri kaa upayog karke cumm bijli kaa upbhog curr sakate hain. spin transister kii badhee hui samvedansheelta parr bhee adhik samvedansheel motor vaahan samvedak banaane mein shodh kiya jaa rhaa haye, ack kadam jise paryaavaran key anukool vaahanon key liye ack dhakka dwara protsaahit kiya jaa rhaa haye.
spin transister kaa doosara laabh yeh haye kii ack electron kaa spin ardh-sthaayi hotaa haye aur iska upayog laagat prabhaavi gair-vashpasheel thhos avastha bhandaran banaane key saadhan key roop mein kiya jaa sakata haye jise banaae rakhane key liye dhaara key nirantar anuprayog kii aavashyakta naheen hoti haye. yeh chumbakiya yaadrichhik abhigam smriti (aim. aar. aim.) key liye khoji jaa rahee takneekon mein seey ack haye.
computer kii duniya mein vyaavhaarik upayog key liye isaki uchch kshamata key kaaran, spin transister parr vartamaan mein duniya bhar kii vibhinn farmon mein shodh kiya jaa rhaa haye, jaise kii ingland aur sweeden mein. haal kii safaltaon ney spin transister key utpaadan kii anumati dee haye, aasaani seey upalabdh padarthon kaa upayog karke, joe kamare key tapman parr kaam curr sakate hainh vaanijyik vyavaharyata key liye ack agradoot.
