Abstract: A method for forming CsPbBr3 perovskite nanocrystals into a two-dimensional (2D) nanosheet includes providing CsPbBr3 perovskite nanocrystals; mixing the CsPbBr3 perovskite nanocrystals into a mixture of a first solvent and a second solvent, to form a solution of the CsPbBr3 perovskite nanocrystals, the first solvent, and the second solvent; and forming an optoelectronic device by patterning the CsPbBr3 perovskite nanocrystals into a nanosheet, between first and second electrodes. The first solvent is selected to evaporate before the second solvent.

Abstract: A method for making ion-crystal semiconductor material based micro- and/or nanowires, MNWs, embedded into a semiconductor substrate, includes forming a structure into the semiconductor substrate, wherein the structure has each of a width and a depth less than 10 μm; pumping an ion-crystal semiconductor material as an ion solution into the structure, wherein the pumping is achieved exclusively due to capillary forces; flowing the ion solution through the structure to fill the structure; crystallizing the ion-crystal semiconductor material inside the structure to form the MNWs; and adding electrodes to ends of the MNWs.
