Abstract
(EN)
Some embodiments include an integrated assembly having a semiconductor material with a more-doped region adjacent to a less- doped region. A two-dimensional material is between the more-doped region and a portion of the less-doped region. Some embodiments include an integrated assembly which contains a semiconductor material, a metal-containing material over the semiconductor material, and a two-dimensional material between a portion of the semiconductor material and the metal-containing material. Some embodiments include a transistor having a first source/drain region, a second source/drain region, a channel region between the first and second source/drain regions, and a two-dimensional material between the channel region and the first source/drain region.

Certains modes de réalisation de l'invention comprennent un ensemble intégré comportant un matériau semi-conducteur pourvu d'une région plus dopée, adjacente à une région moins dopée. Un matériau bidimensionnel se situe entre la région plus dopée et une partie de la région moins dopée. Certains modes de réalisation comprennent un ensemble intégré qui contient un matériau semi-conducteur, un matériau contenant du métal par-dessus le matériau semi-conducteur, et un matériau bidimensionnel entre une partie du matériau semi-conducteur et le matériau contenant du métal. Certains modes de réalisation comprennent un transistor comportant une première région de source/drain, une seconde région de source/drain, une région de canal entre les première et seconde régions de source/drain, et un matériau bidimensionnel entre la région de canal et la première région de source/drain.
