Metric Options: Counts1 Year3 YearSelecting 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
The current theoretical study explores the physical properties of quaternary Heusler ferrimagnetic semiconductors, specifically CrVTiAl, CrVZrAl, and CrVHfAl. Using first-principles calculations, we conduct a comprehensive analysis of the structural, electronic, and thermoelectric properties at different temperatures ( 300K, 600K, and 900K ) employing the r 2 SCAN functional. Furthermore, we investigate the impact of various types of doping on thermoelectric performance and efficiency of these Heusler compounds. Our results demonstrate the tunability of the thermoelectric properties of these Heusler compounds, emphasizing the critical role of carrier concentration, and provide valuable insights for the design and improvement of thermoelectric properties for thermoelectric applications.
