Integrated Assemblies Having Polycrystalline First Semiconductor Material Adjacent Conductively-Doped Second Semiconductor Material

Abstract:

Some embodiments include an integrated assembly having a polycrystalline first semiconductor material, and having a second semiconductor material directly adjacent to the polycrystalline first semiconductor material. The second semiconductor material is of a different composition than the polycrystalline first semiconductor material. A conductivity-enhancing dopant is within the second semiconductor material. The conductivity-enhancing dopant is a neutral-type dopant relative to the polycrystalline first semiconductor material. An electrical gate is adjacent to a region of the polycrystalline first semiconductor material and is configured to induce an electric field within said region of the polycrystalline first semiconductor material. The gate is not adjacent to the second semiconductor material.
