The use of bulk effective masses in simulations of the modern-day ultra-scaled transistor is erroneous due to the strong dependence of the band structure on the cross-section dimensions and shape. This has to be accounted for in transport simulations due to the significant impact of the effective masses on quantum confinement effects and mobility. In this article. we present a methodo... https://www.roneverhart.com/Farmhouse-Magnolia-Wreaths-Pick-Your-Size/
