22.1.5 The Work Function - Save My Exams
Web14 jul. 2013 · Calculate the work function of the metal. I did this: E=Ek+W W=E+Ek W=hc/Lambda -Ek = (6.63E-34J.s) (3.00E8m/s)/3.50E2m)-1.20eV =-1.2 That answer is … WebThe physical principle for UPS characterization of the work function is straightforward, as is schematically summarized in Figure 1, for metals (a) and semiconductors (b), respectively. The photon energy, hν, is the sum of the kinetic energy (KE) and the binding energy (BE) of photoemitted electrons, on the basis of energy conservation. how to make a scenery in photoshop

Web24 feb. 2012 · Work Function Formula The gain of kinetic energy of an electron is the difference between incident photon energy and work function of the metal or material … Web12 nov. 2014 · So use, (hc/wavelength) = workfunction + K.E of Energy of electron. Now workfunction is given, convert it to J. Then the velocity of electron is given, so find out … WebIn 1971, Lang and Kohn were able to get work functions of simple metals to about 5% and noble metals to 15%. I think it would be possible to reproduce these calculations today quite easily. A more recent paper (2005) by Da Silva, Stampfl, and Scheffler uses all-electron first principles calculations, as opposed to the more empirical fitted pseudopotential … how to make a scatter point graph on excel
