    摘要: An electromagnetic wave detector includes a semiconductor layer, a two-dimensional material layer, a first electrode portion, a second electrode portion, and a ferroelectric layer. Two-dimensional material layer is electrically connected to semiconductor layer. First electrode portion is electrically connected to two-dimensional material layer. Second electrode portion is electrically connected to two-dimensional material layer with semiconductor layer interposed therebetween. Ferroelectric layer is electrically connected to at least any one of first electrode portion, second electrode portion and semiconductor layer. Electromagnetic wave detector is configured such that an electric field generated from ferroelectric layer is shielded with respect to two-dimensional material layer. Alternatively, ferroelectric layer is arranged so as not to be overlapped with two-dimensional material layer in plan view.

    摘要: The invention provides an optoelectronic device comprising a photoactive region, which photoactive region comprises: an n-type region comprising at least one n-type layer; a p- type region comprising at least one p-type layer; and, disposed between the n-type region and the p-type region: a layer of a perovskite semiconductor without open porosity. The perovskite semiconductor is generally light-absorbing. In some embodiments, disposed between the n-type region and the p-type region is: (i) a first layer which comprises a scaffold material, which is typically porous, and a perovskite semiconductor, which is typically disposed in pores of the scaffold material; and (ii) a capping layer dis -posed on said first layer, which capping layer is said layer of a perovskite semiconductor without open porosity, wherein the perovskite semiconductor in the capping layer is in contact with the perovskite semiconductor in the first layer. The layer of the perovskite semiconductor without open porosity (which may be said capping layer) typically forms a planar heterojunction with the n-type region or the p-type region. The invention also provides processes for producing such optoelectronic devices which typically involve solution deposition or vapour deposition of the perovskite. In one embodiment, the process is a low temperature process; for instance, the entire process may be performed at a temperature or temperatures not exceeding 150° C.
