Determine the metal-semiconductor work function difference øms in a MOS structure with p-type silicon for the case when the gate is (a) aluminum, (b) n- polysilicon, and (c) p+ polysilicon. Let Na = 6 × 10^15 cm^-3.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Find the minimum film thickness for a journal bearing with the data below. shaft diameter, d-50 mm, clearance ratio, cdratio? 0.001, shaft speed, n 2000 rpm; bearing length. i 200 mm; eccentricity ration, ? -0.55. ( note, cdratio-ca/d) the minimum film thickness is um

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
