LEEM-8 Magnetoresistive Effect Experimental Apparatus

Tsanangudzo Pfupi:

Cherechedza: oscilloscope haina kubatanidzwa

Chigadzirwa chacho chiri nyore mukugadzirisa uye chakapfuma mune zvinyorwa.Inoshandisa marudzi maviri emasensa: GaAs Hall sensor kuyera iyo magineti induction intensity, uye kudzidza kuramba kweInSb magnetoresistance sensor pasi peyakasiyana magineti induction intensity.Vadzidzi vanogona kuona iyo Horo mhedzisiro uye magnetoresistance mhedzisiro ye semiconductor, iyo inoratidzirwa nekutsvagisa uye dhizaini kuyedza.

Miedzo

1. Dzidza kuramba shanduko yeInSb sensor vs iyo yakaiswa magineti intensity;tsvaga empirical formula.

2. Plot InSb sensor resistance vs magnetic field intensity.

3. Dzidza maitiro e AC eInSb sensor pasi pesimba remagineti risina simba (frequency-doubling effect).
