Stress originates from… Thermal expansion coefficient difference?

  4. J. Appl. Phys., Vol. 55, No. 4, 909 (1984) Stress originates from… • Volume expansion by selenization? • Volume expansion >100% by selenization • In the direction perpendicular to the interface, the selenide being free • In-plane ~35% linear expansion will be difficult. The interface will be subjected to a plane stress. Selenide • In-plane compressive stress • Decreased cation vacancy concentration • Diffusion of Ga toward bottom Precursors Mo Glass
