2D Semiconductor Materials Creep Toward Manufacturing
By Katherine Derbyshire - 16 Feb, 2023 - Comments: 0

As transistors scale down, they need thinner channels to achieve adequate channel control. In silicon, though, surface roughness scattering degrades mobility, limiting the ultimate channel thickness to about 3nm. Two-dimensional transition metal dichalcogenides (TMDs), such as MoS2 and WSe2, are attractive in part because they avoid this limitation. With no out-of-plane dangling bonds and at... » read more
