(25 pоints) An оhmic cоntаct requires heаvy doping into the semiconductor to creаte a significant tunneling current. Now you have n-type Si and a choice between two metals: gold (Au) and titanium (Ti). (a) What is the ideal Schottky barrier height for electrons between Au and Si, and between Ti and Si? (10 points) (b) With a low doping level in Si, i.e. tunneling current is negligible and thermionic emission current dominates, what is the specific contact resistance for Au on n-type Si at 300 K? (5 points) (c) You find that by heavily doping n-type Si with Nd = 2×1019 cm–3, tunneling current dominates and the specific contact resistance for Au on n-type Si satisfies your device requirements. You also find that Au is expensive, and you have to go with Ti. Now what is the doping level required in n-type Si to achieve the same specific contact resistance as for Au/Nd = 2×1019 cm–3 case? (10 points)
