The figure above shows the absorption spectrum of the molecule HBr. Following the basic procedures of Section 9.6, find:(a) the energy of the “missing” transition;(b) the effective force constant k;(c) the rotational spacing 2B. Estimate the value of the rotational spacing expected for HBr and compare with the value deduced from the spectrum. Why are there only single lines and not double lines as in the case of HCl?
To improve the semiconducting characteristics of GaAs, 1.31 x 10^15 atoms of Be are incorporated into the material. Be has an ionization energy of 0.6eV.
What is the concentration/s of the majority and minority charge carrier?
Integrated circuits are composed of very high purity silicon which is doped with small and highly controlled quantities of Phosphorus (group VA) and Boron (group IIIA). For Silicon that has been doped with B with the concentration of 6.5E21 atoms per cubic meter, compute the (a) weight percent and (b) the atom percent of B present.
