JC-29) Range of the Nuclear Force We can make an estimate of the range of the nuclear force by considering the following process. A proton or neutron can sometimes “violate" conservation of energy by emitting and then reabsorbing a pi meson (T), which has a mass of 135 MeV/c². This is possible as long as the pi meson is reabsorbed within a short enough time At consistent with the uncertainty principle. Consider p -->p+t. By what amount AE is energy conservation a) violated? (Ignore any kinetic energies.) For how long a time At can the pi meson exist? b) c) Assuming the pi meson travels at very near the speed of light, how far from the proton can it go?

Determine the thermal equilibrium electron and hole concentrations in a compensated n- type semiconductor. Consider a silicon semiconductor at T = 300°K in which Na = 10° cm³ and Na = 3 x 105 cm. Assume that n; =1.5 x 10º cm?.
The dependence of drift velocity of electrons on electric field in a semiconductor is shown below. The semiconductor has a uniform electron concentration of n = 1 × 10¹6 cm-3 and electronic charge q = 1.6 × 10-19 C. If a bias of 5 V is applied across a 1 µm region of this semiconductor, the resulting current density in this region, in kA/cm², is Drift velocity (cm/s) 10 linear constant 5x10 Electric field (V/cm)

Please provide Handwritten answer. 9. After following all the steps in the photolithography, a student found that all the photoresist (the exposed and unexposed photoresist) on the silicon wafer was washed away during the development step. This is due to... * A) the student used longer exposure time during alignment and exposure step B) the student used slower spin speed during spin coating producing thicker photoresists C) the student used longer development time during the development step D) the student used lower temperature and shorter baking time during the pre bake step E) the student misaligned the mask with the wafer during the alignment step 10. After photolithography process the wafer will go to the either etching process or doping process such as ion implantation and diffusion. * True or False
20. A biased clamper is connected to a rectangular AC input with 20V on the positive half cycle and -10V on the negative half cycle. The orientation of the Si diode is the same with Vo while the 5V biasing voltage is in opposite connection. The value of R is 100K ohms while the capacitor is 1 microFarad.

The original diode equation was derived by William Shockley in 1949 to model the behaviour of germanium diodes. A few years later it was modified to account for the differences between germanium and silicon diodes by including an ideality factor n. This produced the form of the diode equation that you will now be familiar with: eV 1 = 1₁ [exp()-1] 3) Extend your analysis to extract the reverse saturation current under strong forward bias.
