6- A silicon pnp transistor has impurity concentrations of 5 x 1018 cm3, 7 x 1016 cm-3, and 2 × 1016 cm-3 in the emitter, base and collector, respectively. The base width is 1.0 ?m, and the device cross-sectional area is 0.2 mm2. When the emitter-base junction is forward biased to 0.5 V and the base-collector junction is reverse biased to 5 V, calculate the neutral base width and the minority...

1) Light of wavelength 310nm is shined on a metal with work function = 1 eV. What will be the maximum kinetic energy of the emitted electrons? 2) Light is shined on a metal with work function 2.0 eV, and electrons are emitted creating a photocurrent. When a decelerating voltage of magnitude 1.0 V is applied, the current goes to zero (i.e. the magnitude of the stopping voltage is 1V). What is the wavelength (in nm) of the incoming light?...

(1 point) A Silver surface (work function = 4.26 eV) is illuminated with 270 nm light from a 3 mW laser. How many photons per second are emitted by the laser? 4.0909E15 photons/s Only a small fraction of these photons can interact with electrons at the surface. Suppose this fractional efficiency is 0.00031%. What is the current in the detector assuming all the emitted electrons are captured? пA Note that current is charge(in Coulombs) per second. The charge of one...
