Physics Syllabus For Grade 12
... The study of both sound and optics is based on knowledge of the nature of waves. On lectures emphasis should be on the fact that energy can be transmitted in only two ways – either by transfer of particles or by waves. Stress that all waves have the same general properties and follow the same laws i ...

... A semiconductor diode is a silicon or germanium crystal of which part (p-type) has been treated so that it has excess positive charges; the other part (n-type) has been treated to have an excess of electrons. If a cell is connected across such a diode, electrons will flow as indicated in the diagram ...

... It means that Neff can be estimated from (3) if the two dielectric constants are known from other independent measurements. The Schottky representation is shown in the inset of Fig. 4 for the true leakage currents (second runs). A value of about 1.8×1019 cm-3 was obtained for Neff. This is one order ...
