LEEM-8 Magnetoresistive Effect Experimental Apparatus

Kev Piav Qhia Luv:

Lus Cim: oscilloscope tsis suav nrog

Cov cuab yeej no yooj yim hauv cov qauv thiab muaj ntau yam ntsiab lus. Nws siv ob hom sensors: GaAs Hall sensor los ntsuas qhov sib nqus induction zog, thiab kawm txog qhov tsis kam ntawm InSb magnetoresistance sensor nyob rau hauv qhov sib txawv magnetic induction zog. Cov tub ntxhais kawm tuaj yeem saib xyuas Hall effect thiab magnetoresistance effect ntawm semiconductor, uas tau piav qhia los ntawm kev tshawb fawb thiab kev tsim qauv sim.

Kev sim

1. Kawm txog qhov kev hloov pauv ntawm lub zog ntawm InSb sensor piv rau qhov siv zog ntawm lub zog magnetic; nrhiav cov mis empirical.

2. Plot InSb sensor tsis kam vs magnetic field intensity.

3. Kawm txog cov yam ntxwv AC ntawm lub InSb sensor nyob rau hauv lub zog magnetic tsis muaj zog (zaus-doubling effect).
