Increased spatial homogeneity in a light-emitting InGaN thin film using optical near-field desorption

Thin film light-emitting devices (LEDs) with sandwich structure, such as organic light emitting devices (OLEDs), quantum dots LEDs (QLEDs) and perovskite LEDs (PeLEDs), have attracted wide attentions because of their...

Non Destructive

A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, and real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed is built up with a handled vector network analyzer interfaced with corrugated horn antennas to measure the near-field complex reflection S11 of planar prepreg composite materials in a roll-to-roll in-line production line. Dedicated modeling and calibrations routines are developed to extract the microwave conductivity from the measured microwave signal. Practical extraction of the radiofrequency (RF) conductivity of thin film prepreg composite materials doped with nano-powders is exemplary shown at the test frequency of 10 GHz.
