Step 1

- Φ_S represents the work function of the semiconductor. - E_C, E_V, and E_F represent the conduction band minimum, valence band maximum, and Fermi level of the semiconductor, respectively. - E_vac is the vacuum level, a reference energy level outside the Show more…

(MS heterojunction) Draw the band diagram (as shown in the picture below) of a heterojunction between metal and p-type semiconductor if Î¦ð‘€ > Î¦ð‘†. Clearly mark ð¸ð‘£ð‘Žð‘, ð¸ð¶, ð¸ð¹, and ð¸ð‘‰ on your diagram. Is this a Schottky contact or an Ohmic contact? (2) s > &M After contact es-M] Evac e&s exs eM Ec EF EF Ev Metal n-type semiconductor M
