From: Effects of Geometry on the Electronic Properties of Semiconductor Elliptical Quantum Rings
The ground state energy level of a confined electron in an elliptical QR as a function of the height amplitude [see the definition of A in Eq. (5)]. Results shown correspond to Rx1 = 20 nm and Ry1 = 25 nm. Calculations include QRs with triangular, parabolic, and squared transversal sections; several values of the number of hills have been taken into account: n = 0 (solid lines), n = 2 (dashed lines), and n = 4 (dotted lines).
