Molecular functionalization of surfaces for device applications

Effective Metal Top Contact on the Organic Layer via Buffer-Layer-Assisted Growth: A Multiscale Characterization of Au/Hexadecanethiol/n-GaAs(100) Junctions

“…OMLs have been considered to selectively modify the work function of metal surfaces or to modify the depletion layer of semiconductors, to act as a nanometer-thick tunnel barrier in both metal/OML/semiconductor and metal/OML/metal junctions, and finally to manipulate spin polarization and magnetic anisotropy at interfaces . In this field of organic and molecular electronics at monolayer coverage, the need for abrupt and well-controlled top metal contacts is a key point. This has been the subject of numerous studies.…”

Studying Molecular Rearrangement of P1 Dye at a Passivating Alumina Surface Using Vibrational Sum‐Frequency Generation Spectroscopy: Effect of Atomic‐Level Roughness

“…Molecular functionalization is widely used to tailor the photophysical properties of the surfaces without affecting the bulk properties of the material. [1] The properties of such functionalized surfaces, e. g. of photoelectrodes in dye-sensitized solar cells (DSSC) or dye-sensitized photoelectrochemical cells (DSPEC), are greatly influenced by the molecular structure and electronic states of the adsorbed molecules, which, by themselves, depend on the molecular assembly and intermolecular interactions of the sensitizers on the electrode surface: e. g. in DSSCs the adsorption mode of the molecular photosensitizers on the TiO 2 surfaces affects the open circuit potential. [2] Therefore, continuous attempts are made to opti-mize molecular adsorption, orientation, and ordering to finetune the overall efficiency of photoelectrodes.…”
