A pn junction is formed from two different semiconducting materials that are in the form of identical cylinders with a radius 0.165 mm. Suppose that 3.50 × 1015 electrons flow each second across the junction from the n side to the p side while 2.25 × 1015 ‘holes’ flow each second from the p side to the n side. A ‘hole’ is a missing electron amongst the valence electrons, which can be treated as a particle with a charge +e.

14. Consider the following income/expenditure diagram in the simple Keynesian model. $C, I, G, S, T$ $Y = C + S + T$ $C + I + G$ y<sup>e</sup> If taxes, $T$, were increased, then Y a. The $Y = C + S + T$ line would shift to the left, and $Y^e$ would decrease. b. the $C + I + G$ line would shift downward, and $Y^e$ would decrease. c. The $Y = C + S + T$ line would shift to the right, and $Y^e$ would increase. d. the $C + I + G$ line would shift upward, and $Y^e$ would increase. e. neither of the lines would shift, and $Y^e$ would stay the same.

Question 4: [6+6+4=16 Marks] Under a Lorentz transformation $\Lambda$, the Dirac field $\psi(x)$ transforms as $\psi(x) \rightarrow \tilde{\psi}(\tilde{x}) = S(\Lambda)\psi(s)$ were the 4x4 matrix $S(\Lambda)$ satisfies $S^{-1}(\Lambda)\gamma^\mu S(\Lambda) = \Lambda^\mu_{\nu}\gamma^\nu$ (a) Find how the following quantities transforms by applying the Lorentz transformation, where $\gamma^5 = i\gamma^0\gamma^1\gamma^2\gamma^3$ (i) $\bar{\psi}(x)\gamma^5\psi(x)$ (ii) $\bar{\psi}(x)\gamma^5\gamma^\mu\psi(x)$ (b) Also check that, by applying parity transformation, $\bar{\psi}(x)\gamma^5\psi(x)$ transforms as pseudo-scalar, while $\bar{\psi}(x)\gamma^5\gamma^\mu\psi(x)$ transforms as axial vector. (c) Show that the adjoint spinors $\bar{u}^{1,2}$ and $\bar{v}^{1,2}$ satisfy the equations $\bar{v}\gamma^\mu p_\mu + m = 0, \bar{u}\gamma^\mu p_\mu - m = 0$
