Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In the present work, we have studied the effects of the impurity and cross-sectional shape on entropy of different quantum wires. For this goal, we have considered GaAs/Ga In As quantum wires with different cross-sectional shape like circular, hexagonal, square and triangular. To this end, we have computed the energy levels using the finite element method and the Arnoldi algorithm. Using the energy levels, the entropy of quantum wires has been determined by Tsallis formalism. Our results show that the highest and lowest entropy corresponds to circular and triangular quantum wires, respectively. The entropy in the presence of impurity is decreased due to the reduction disorder.
