Assemblies displaying differential negative resistance, semiconductor constructions, and methods of forming assemblies displaying differential negative resistance

摘要

The invention includes a device displaying differential negative resistance characterized by a current-versus-voltage profile having a peak-to-valley ratio of at least about 9. The invention also includes a semiconductor construction comprising a substrate, and a first layer over the substrate. The first layer comprises Ge and one or more of S, Te and Se. A second layer is over the first layer. The second layer comprises M and A, where M is a transition metal and A is one or more of O, S, Te and Se. A third layer is over the second layer, and comprises Ge and one or more of S, Te and Se. The first, second and third layers are together incorporated into an assembly displaying differential negative resistance. Additionally, the invention includes methodology for forming assemblies displaying differential negative resistance, such as tunnel diode assemblies.
