The following parameters of an ideal metal-semiconductor contact are known: 5eV for metal work function, 4.05eV for semiconductor electroaffinity, effective density of states for conduction band is 1019cm3, n-type doping density is 1015cm3, semiconductor dielectric constant is 11.8.(a) draw its energy band diagram with proper labeling.(b) calculate the built-in potential and barrier height if it is a Schottky barrier or if it is not rectifying explain why.(c) calculate the depletion width and the corresponding capacitance at zero bias.(d) describe a general method step-by-step that can be used to determine the built-in potential and Schottky barrier height of a Schottky barrier diode
a) Evaluate % overshoot, settling time and peak time if a=4 and b=25 b) Calculate values of a&b so imaginary part of poles remains same but real part increased by 2 times
Using the table, what is the byte stored at address 2F? Using the table, what is the byte stored at address 33?
An Ideal Low Pass Filter: The impulse response of an ideal low-pass filter is h(t) = sin(t)/t (or the sinc signal). (a) Given that the impulse response is the response of the system to an input x(t) = f(t)with zero initial conditions
The steering wheel has backlash. This means there is a delay between the time the wheel is turned, and the time the car responds. The driver tends to overturn, which leads to instability and lack of control of the car.
Which of the following provides the basic attributes and behaviors of a Java window - a title bar at the top of the window and buttons to minimize, maximize, and close the window JLabel JFrame JSwing
Sketch the complete Nyquist diagram for the following open-loop transfer function. Determine the effect of K on the closed-loop stability. Explain how the "shortcuts" contribute to the diagram.
Contains basic function in MATLAB files. Write MATLAB script(s) to plot the basic signals below in two subplots. The upper subplot should be a continuous waveform (don't do g) and the lower subplot should be a discrete plot.
Discuss the operation of a JFET, including the pinch off and gate-source cutoff voltage in your explanation. Discuss how you can tell whether an FET is operating in the ohmic region or the active region.
A parallel-plate capacitor is charged to a potential V0, charge Q0 and then disconnected from the battery. The separation of the plates is then halved. What happens to (a) the charge on the plates
Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. Find the probability that the screws drawn will be nondefective in drawing (a) with replacement, (b) without replacement.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
A wave in free space has a wavelength of 12 cm. This wave reaches a material in which the transmitted wave has a wavelength of 8 cm. lEl= 10V/m and lHl= 100 mA/m. Find the frequency of the wave, along with the permitivity and permeability of the m..
