Consider cryogenically cooled Si semiconductor doped with an unknown dopant type a dopant concentration Ndop. Based on the below measured carrier concentration (n or p) a Hall coefficient Ry values as functions of temperature, find out the doping type (n- or doping), the doping concentration Ndop, and the ionization energy (Ed or E.). Finally, bas on the ionization energy, make an educated guess of what element the dopant could have bee 10-2 1026 103 10 25 104 1024 Carrier concentration [1/m $] Hall coefficient R [1/(C . m )] 10-5 1023 106 1032 1074 30 35 40 45 50 55 60 65 70 75 80 10 31 Temperature T (K)
