We control the work function and the surface energy of the MoO3/Au/MoO3 (MAM) anode of OLEDs by modifying the top MoO3 layer via vapor phase deposition. The performance and stability of the device are significantly altered depending on the dipole dir

An efficient process for the low contact resistance and adherent source/drain Au electrode in bottom-contact organic thin film transistors (OTFTs) was developed. This was achieved by using two different surface-functional groups of self-assembled mon

Two types of source/drain (S/D) electrodes, formed of poly(3,4-ethylenedioxythiophene):p-toluenesulfonate (PEDOT:PTS) conducting polymer and Au, were fabricated and mounted on flexible pentacene transistors. Several properties of the S/D electrodes w

A MoO3/Au/MoO3 structure with a protective barrier Al2O3 was developed to suppress the reactions between MoO3 and the PEDOT:PSS film in organic solar cells (OSCs). Though the maximum optical transmittance of this structure was 66% at 550 nm wavelengt

We investigated the effects of solvents, such as ethanol and isooctane, on self-assembly of the mercaptoundecanoic acid (MUA) monolayer on Si and its diffusion barrier properties for Cu metallization. The use of isooctane as a solvent produced MUA se

Sputtering of indium tin oxide (ITO) on pure Al substrate produces an Al 2 O 3 layer at the interface, leading to Schottky contact characteristics. A very small amount of Ni (2 at.% Ni) added to Al drastically reduces the contact resistance of an ITO
