Ms contacts - energy-band diagrams a number of ms contacts are formed on si substrates maintained at t = 300k. for each of the contacts listed below, draw the energy-band diagram (indicating the schottky-barrier height db, the depletion- layer width w, ec - ef in the neutral region, and the built-in potential v bi ), and indicate whether the contact is ohmic or rectifying: a) an ideal contact between al ((pm= 4.1ev) and n-type silicon with np = 1017 cm3, va= 0v b) an ideal contact between al (pm= 4.1ev) and p-type silicon with na = 1017 cm3, va= 0 v. c) an ideal contact between al (pm=4.1ev) and p-type silicon with na = 1017cm3, va= -0.5 v. d) a contact between nisi and n-type silicon with np = 1017 cm3, with va= 0 v. e) a contact between nisi and p-type silicon with na = 1017cm3, with va= 0 v. note: for the nisi contacts, use the schottky barrier values given in lecture notes

Eddy whose mass is 55kg climbs up the 1.50 meter high stairs in 2s. calculate eddy’s power rating

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
