  1. EE 5340Semiconductor Device TheoryLecture 1 - Fall 2003 Professor Ronald L. Carter ronc@uta.edu http://www.uta.edu/ronc

  2. Web Pages • Bring the following to the first class • R. L. Carter’s web page • www.uta.edu/ronc/ • EE 5340 web page and syllabus • www.uta.edu/ronc/5340/syllabus.htm • University and College Ethics Policies • www2.uta.edu/discipline/ • www.uta.edu/ronc/5340/COE_EthicsStatement_Fall02.htm

  3. First Assignment • Send e-mail to ronc@uta.edu • On the subject line, put “5340 e-mail” • In the body of message include • email address: ______________________ • Your Name*: _______________________ • Last four digits of your Student ID: _____ * Your name as it appears in the UTA Record - no more, no less

  4. Quantum Concepts • Bohr Atom • Light Quanta (particle-like waves) • Wave-like properties of particles • Wave-Particle Duality

  5. Bohr model forHydrogen atom • Electron (-q) rev. around proton (+q) • Coulomb force, F = q2/4peor2, q = 1.6E-19 Coul, eo=8.854E-14Fd/cm • Quantization L = mvr = nh/2p, h =6.625E-34J-sec

  6. Bohr model for the H atom (cont.) • En= -(mq4)/[8eo2h2n2] ~ -13.6 eV/n2 • rn= [n2eoh2]/[pmq2] ~ 0.05 nm = 1/2 Ao for n=1, ground state

  7. Bohr model for the H atom (cont.) En= - (mq4)/[8eo2h2n2] ~ -13.6 eV/n2 * rn= [n2eoh2]/[pmq2] ~ 0.05 nm = 1/2 Ao * *for n=1, ground state

  8. Energy Quanta for Light • Photoelectric Effect: • Tmax is the energy of the electron emitted from a material surface when light of frequency f is incident. • fo, frequency for zero KE, mat’l spec. • h is Planck’s (a universal) constant h = 6.625E-34 J-sec
