An N-type silicon substrate with the doping density of 1x10 15 cm-3 Arsenic is to be converted into p-type by Boron diffusion, so that the resistivity at T=75C is 5 O-cm. All atoms are fully ionized.
Assume that a given transformer is 100% efficient; that is, the power being supplied by the primary side is transported without loss to the secondary side. (Transformers are not 100% efficient. One can detect this by the heat that they radiate.)
Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3 or 1.00 g/mL) as water, calculate the heat (in J) transferred to the surroundings, qsurr.
