Show transcribed image text An isotype step junction is one in which the same impurity type doping changes from one concentration value to another value. An n-n isotype doping profile is shown in Figure P7.12.
(a) Sketch the thermal equilibrium energy-band diagram of the isotype junction.
(b) Using the energy-band diagram. determine the built-in potential barrier.
(c) Discuss the charge distribution through the junction.
a 150 kg mass is suspended by wires from two hooks. the lengths of the wires have been adjusted so that the wires are each 50º from horizontal. assume that the mass of the wires is negligible.
A room is filled with saturated steam at 100 degrees C. Now a 5-kgbowling ball at 25 degrees C is brought to the room. Heat istransferred to the ball from the steam, and the temperature of the
Diesel fuel has an average chemical formula of C12H23 and a density of 6.45 lb/gal. Calculate how many lbs of CO2 are produced per gallon of diesel burned (assume complete combustion).
A 25 mm diameter steel cylinder falls under its own weight at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. Castor oil of viscosity 0.25 N.s/m2 fills the spacing between the tube and the cylinder.
For a two-dimensional ideal fluid flow, write the continuity equation and the Navier-Stokes equations (in the two components) in Cartesian coordinates and in polar coordinates.
Two rectangular clarifiers(sedimentation basins), each 30 ft long, 15 ft wide, and 10ft deep, settle a combinedtotal of 0.40 mgd following alum coagulation. The effluent channelshave a total weir length of 60ft in each basin
A sag vertical curve along an existing vertical alignment begins at station 23+45 and ends at station 30+25. The initial grade coming into the curve is -2% and the grade out is +5%. What is the finished grade elevation on the curve at station
A sprinkler system uses an outdoor reservoir at El 50. A fire pump moves Q = 3 ft^3/sec through a 1.0' dia pipe 300' long to an 8" dia main at El 200. To distribute water to sprinklers, a pressure head at the pipe junction hp =100' is required.
Pure water at 50 degrees Fahreneit stands in a glass tube of 0.04-in diameter at a height of 6.78 in. Compute the true static height.
The atomic radius for iron has been measured to be 0.1241 nm. Determine the interplanar spacings for the (111) and (211) sets of planes
A very long rectangular channel connects two reservoirs and has a longitudinal slope of 0.005. The channel has a width of 10 m and a Manning's n of 0.030.
Why don't we assume that there is an unknown moment about B? It the solution it only shows a horizontal force at B. And is there a reason why the horizontal force at B is labeled By?
