Objectives: Quantum wires are one-dimensional (1-D) material that exhibit length to width ratios of about 1000 or more. The properties of quantum wire are due to the electrons in them have quantized energy levels perpendicular to their lengths. Such quantum confinement effect exhibits discrete values of electrical conductance which are integral multiples of (e2 /h). Methods/ Analysis: In this paper we present a quantum mechanical analysis of evaluation of the electron energy eigen states and their corresponding eigen functions in a quantum wire of circular cross-section. Findings: The energy eigen values of quantum wires of different radii are calculated. Applications: On the basis of our preliminary analysis it has been observed that quantum wires can also be used as electronic energy filters.
