Isisetshenziswa Sokuhlola Somphumela We-Magnetoresistive se-LEEM-8 Isithombe Esifakiwe

Imishini Yokuhlola Yomphumela We-Magnetoresistive we-LEEM-8

Incazelo emfushane:

Qaphela: i-oscilloscope ayifakiwe

Le divayisi ilula ngesakhiwo futhi inokuqukethwe okuningi. Isebenzisa izinhlobo ezimbili zezinzwa: inzwa ye-GaAs Hall ukukala ukuqina kokufakwa kwe-magnetic, kanye nokufunda ukumelana kwenzwa ye-InSb magnetoresistance ngaphansi kokuqina okuhlukile kokufakwa kwe-magnetic. Abafundi bangabona umphumela we-Hall kanye nomphumela we-magnetoresistance we-semiconductor, obonakala ngocwaningo nokuhlolwa kokuklama.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa

1. Funda ushintsho lokumelana kwenzwa ye-InSb uma kuqhathaniswa nokuqina kwensimu yamagnetic esetshenzisiwe; thola ifomula ye-empirical.

2. Ukumelana kwenzwa ye-InSb vs amandla ensimu yamagnetic.

3. Funda izici ze-AC zenzwa ye-InSb ngaphansi kwensimu yamagnetic ebuthakathaka (umphumela wokuphindaphindwa kwemvamisa).
