5. (а) I hаve twо n-type GаAs samples that are cоntacted tо gold. Sample A has a n-type doping level of 1E16 cm-3 and Sample B has a doping level of 3E17 cm-3. Other than doping, the structure is the same. Which sample has the smaller built-in potential (known as Vbi or V0) at equilibrium? Support your answer for full credit. Also given: GaAs = 4.1 eV, Au = 5.3 eV (b) For sample A, I try out some different metals (Al: work function 4.3 eV, Ni: work function: 4.5, Cu: work function 4.7 eV, Pt: work function 5.65 eV) and measure my barrier height. I get a repetitive 0.8 eV regardless of the metal. Why?
