3 Lumpy Junction A thermocouple junction, which may be approximated as a sphere, is to be used for temperature measurement in a gas stream. The convection coefficient between the junction surface and the gas is h = 200 W m-2 K-1. The junction properties are k = 35 W m-1 K-1, c = 500 J kg-1 K-1, and p = 8000 kg m-3. Determine the junction diameter needed for the thermocouple to have a time constant of t = 0.8...

4- Consider a siliconpn-junction: a) Draw the hand diagram indicating the valence hand, the conduction hand, te rmi energy, and the buil- in potentiul, V ussuming that no voltuge is upplied across the junction. Indicate on this diagram approximately where the depletion region would be. (High level of acuracy is expected in this question). h) The doping is Na = 8x10 I cm? and N, = 2x10 lenN. At 300 K, what is the concentration of holes nn the p-side...

1) Describe PN junction under equilibrium, forward, and backward bias conditions. Draw the band diagram together with charge density, electric field, and potential profiles across the junction. Describe the physics of charge transport (both electrons and holes) in PN junction under forward bias. Include drift, diffusion, recombinations etc in your description.

1. Draw all the significant resonance forms for the following structures, and indicate which are major and which are minor, or if you have two equally important forms, say so. The number of new forms you need to draw is shown in parentheses below the arrow. (a) N co 4. In each of the following reactions, indicate which structure is the nucleophile and which is the electrophile. Also draw the products (use the electron pair arrows to guide you). (a)...
