Fabrication and characterization of silicon-on-insulator wafers
Four probes are connected to the silicon island of the SOI wafer where the pseudo-MOSFET was measured (center of Fig. 4d). When a magnetic field is applied perpendicular to the SOI wafer, a current is passed through two of the probes, and the voltage is measured across the other two. From the measured voltages, the Hall voltage, which allows us ...

Voltage Losses due to Recombination
The open-circuit voltage is the voltage at which the forward bias diffusion current is exactly equal to the short circuit current. The forward bias diffusion current is dependent on the amount of recombination in a p-n junction and increasing the recombination increases the forward bias current. Consequently, high recombination increases the forward bias diffusion current, which …
