ABSTRACTA simple ratio technique using the phenomenon of electron channeling can be used to measure the substitutional concentrations of dopants in semiconductors on a submicron scale.A comparison was made between electron and ion channeling measurements on Si-Sb alloy samples having a range of nonsubstitutional fractions of Sb.Good agreement was obtained but both measurements indicated considerably more nonsubstitutional dopant than could be accounted for by precipitates observed in electron micrographs. The discrepancy can be explained if the precipitates are coherent in the early stages of growth and have their planes located interstitially with respect to the Si planes. The sensitivity of the electron channeling measurements to the implantation profile was investigated and found to be small.The determination of local dopant profiles in the electron microscope is described.

The Basin Of Attraction

In this paper we study the experimental determination of the basin of attraction for the Chua's circuit by means of an electronic device that is able to select initial voltages and to show the early stages of the subsequent trajectory on the oscilloscope. The results are shown and discussed in cases of multistability of periodic and chaotic solutions.
