An Electron's Longings The electron at the edge of the valence band said: I stand upon the edge Condemned by fate's cruel hand To lie in a state of perpetual freeze With energy lacking to do a trapeze Across to freedom's higher land There are many who have risen beyond Coulombic forces. They blisfully exist Unshelled. Their orbitals know no bond. With carefree abandon they diffuse and drift. Will no photon shine a light ? Will no dopant lend a hand ? To conquer Fermi's improbable height To leap into the conduction band !
