Two-dimensional colloidal nanomaterials represent very exciting optoelectronic properties. The formation of ordered and densely packed surface layers of amphiphilic ligand molecules on certain crystal facets can drive the normally isotropic into a two-dimensional crystal growth, resulting in semiconducting nanosheets. Such structures combine good lateral conductivity with solution-processability and electronic confinement in height, which allows tuning the effective bandgap of the materials. I will present the syntheses of the materials and the analyses of the optoelectronic transport through these materials in field-effect transistors, solar cells, and spintronic devices. It turns out that the electronic confinement allows for an optimization of their performances.
