Khoom taw qhia
Lub DX-9000 series hluav taws xob thauj khoom ntsuas qhov system yog lub tshuab ntsuas hluav taws xob tag nrho uas ua ke nrog Hall effect, magnetoresistance, hloov pauv kub tsis kam, IV yam ntxwv thiab lwm yam kev sim.
Lub kaw lus txiav txim siab txog cov teeb meem uas cov neeg siv feem ntau tsis saib xyuas, xws li kev sib koom ua ke, kev tiv thaiv thiab kev cuam tshuam kev cuam tshuam, kev ntsuas hluav taws xob thiab cov qauv kev tiv thaiv ntau qhov sib txuam. Kev ntsuas hluav taws xob los ntawm Keithley hauv Tebchaws Meskas raug xaiv. Lub teb sib nqus txais electromagnets los yog kua helium-dawb superconducting hlau nplaum raws li cov neeg siv xav tau. Nws yog txawm peem rau nrog ib tug ntse ntsuas qauv pas nrig thiab ceev-plug qauv daim ntawv, ntxiv rau tag nrho automated tshwj xeeb kuaj software, ua rau lub lag luam ntau tus neeg siv-phooj ywg. , tso cai rau cov neeg siv kom sai thiab yooj yim ua cov kev ntsuam xyuas hluav taws xob thauj mus los thiab tau txais cov ntaub ntawv raug thiab txhim khu kev qha.
Tsis tas li ntawd, DX-9000 series hluav taws xob thauj khoom ntsuas qhov system muaj ntau yam kev xaiv qhov kub thiab txias ib puag ncig, uas yog cov cuab yeej muaj zog rau cov kws tshawb fawb tshawb fawb los kawm txog hluav taws xob thauj khoom ntawm cov khoom.
Kev ua haujlwm ntawm hluav taws xob thauj khoom ntsuas qhov system
- Ntsuas cov nyhuv Hall, RH yam ntxwv, RT yam ntxwv thiab IV yam ntxwv (resistivity);
- Tsis muaj peev xwm muab tau los ntawm: daim ntawv tsis kam, resistivity, Hall coefficient, Hall txav, carrier concentration thiab conductivity yam;
- Curves tuaj yeem kos:
- Cov kev ntsuas saum toj no hloov nkhaus nrog qhov kub thiab txias lossis sib nqus;
- IV yam ntxwv - IV yam ntxwv nkhaus nyob rau hauv sib txawv magnetic teb thiab txawv kub;
- RH yam ntxwv - qhov kub thiab txias, cov yam ntxwv nkhaus ntawm kev hloov pauv nrog cov hlau nplaum;
- Cov yam ntxwv RT - ruaj khov magnetic teb, cov yam ntxwv nkhaus ntawm kev hloov pauv nrog kub.
Lub ntsiab nta
- Resistivity, Hall coefficient thiab Hall kev txav mus los ua raws li American Society for Testing and Materials ASTM-F76 tus qauv;
