| Zusammenfassung: | We fabricated a magnetic field sensor made of an InAs quantum-well.
Various numbers of magnetic particles were located on the sensor and the stray field generated by the magnetic particles was detected using micro-Hall magnetometry at room temperature.
A numerical calculation carried out for this device successfully explained the experimental results and a useful equation relating the signal of the device and the number of particles was deduced. KCI Citation Count: 5 |
