Energy eigenvalues and density of states of carriers in a finite barrier triangular quantum wire embedded inside a rectangular quantum wire are numerically investigated using finite difference technique (FD-Q). Time-independent Schrödinger's equation is solved with appropriate boundary conditions for computation of lowest three eigenstates. The wire is made of lower bandgap GaAs material surrounded by wider bandgap Al x Ga 1-x As, and the analysis is carried out by taking into consideration of the conduction band discontinuity and effective mass mismatch at the boundaries. The eigenvalues and the density of states are plotted as function of wire dimension and mole fraction (x). The results are also compared with those obtained using rectangular quantum wire.Density of states, Energy eigenvalue, Finite difference technique, Triangular quantum wire.

“…Different numerical methods are already used for computation of energy states of triangular quantum wires. In recent past, it is suggested that finite difference method [6,7] is the most suitable technique for computation of energy levels of semiconductor nanostructures having different potential profiles and different geometries as results are in good agreements with experimental findings.…”

“…In the first model, the quantum wire shows a crescent-like shape and is obtained when [15,16] and many authors have used rectangular cross-section [17,18] to make easy the modelling of such structures. The importance of this method resides in the possibility of its application for different shapes.…”
