A new process for modifying a polymeric material for use as a hole injection transport layer in organic light-emitting diodes has been studied, which is through 2π + 2π photodimerization of a DNA-mimetic π-conjugated poly(triphenylamine-carbazole) presenting pendent uracil groups (PTC-U) under 1 h of UV irradiation. Multilayer florescence OLED (Organic(More)
We describe the development and application of an imaging protocol, which evolves a scanning probe's atomic structure in parallel with automated optimization of the scan parameters. Our protocol coerces the system into a state that produces a specific atomic resolution image type without human involvement. Abstract We use numerical simulations to(More)
In this study, we tethered terminal uracil groups onto short-chain poly(ethylene glycol) (PEG) to form the polymers, uracil (U)-PEG and U-PEG-U. Through AC impedance measurements, we found that the conductivities of these polymers increased upon increasing the content of the lithium salt, LiAsF 6 , until the Li-to-PEG ratio reached 1:4, with the(More)
We demonstrate a new flexible metal–insulator–metal capacitor using 9.5-nm-thick ZrO 2 film on a plastic polyimide substrate based on a simple and low-cost sol–gel precursor spin-coating process. The surface morphology of the ZrO 2 film was investigated using scan electron microscope and atomic force microscope. The as-deposited ZrO 2 film under suitable(More)
Highly (002) oriented aluminum nitride (AlN) films were successfully prepared on a 64deg-YX LiNbO<sub>3</sub> substrate by r.f. magnetron sputtering. The crystalline structure of the films was determined by grazing incident angle X-ray diffraction (XRD) and the surface microstructure of films was investigated by Scanning electron microscope (SEM). The atom(More)
