A rectangular plate of semiconducting material has dimensions of 10 mm x 4 mm x 1 mm. A current of 1.5 mA flows along its length and the associated potential drop is 78 mV. When a magnetic field of 0.7 T is applied normally a potential difference of 6.8 mV appears across the width of the sample. Determine the character, concentration, and mobility of the current carriers.
