According to a new spectroscopy analysis, the adjacent bond vectors was found to be A = 1.07i + 0.83j + 0.81k B = 1.03i + -0.99j + -0.85k What is the angle (in degrees) between the bonds based on this new data?

To obtain the most precise value of BE from the equation BE=[ZM(1H)+ Nmn]c2 − m(AX)c2 , we should take into account the binding energy of the electrons in the neutral atoms. Will doing this produce a larger or smaller value for BE? Why is this effect usually negligible?

Consider a p+-n Si diode with NA = 1018 cm-3 and ND = 1016 cm-3. The hole diffusion coefficient in the n-side is 10 cm2/s and carrier lifetime τp =10-7 s. The device area is 10-4 cm2. Calculate the reverse saturation current and the forward current at a forward bias of 0.7 V at 300 K.
