===== 1. Sommerfeld model (3d FEG)=====

**a)** Assuming the Sommerfeld model, and starting from a sketch of allowed traveling wave states in k-space, show that //n//<sub>//3d//</sub> = (//k//<sub>//F//</sub>)³/3π².

**b)** Estimate //n//<sub>//3d//</sub> and //E//<sub>//F//</sub> for gold using physical/chemical parameters such as density and electron configuration.

===== 2. 2d FEG =====
A&M 2.1 (a)-(d)

===== 3. Maximum surface resistance =====
