Abstract

This paper demonstrates the use of Ultra‐Precise Dispensing, a high‐resolution additive manufacturing method, in the fabrication of Micro‐LED displays. We demonstrate advancements in achieving ultra‐small feature sizes, high aspect ratios, and the ability to print on complex substrates. The paper presents a number of use cases, such as interconnections on complex topographies, edge printing, microvias filling, and microbumps dispensing. It summarizes the relevance of this technology for Micro‐LED displays fabrication and discusses the prospective future developments in the field of additive manufacturing for display fabrication.

Abstract

Combined organic (molecular adsorption) and inorganic (TiO2 passivation) modifications for enhancing water splitting efficiency of porous bismuth vanadate electrodes are tested. The catalytic activity of BiVO4 is increased after adsorption of a newly prepared ruthenium catalyst. TiO2 passivation and sensitization with RuP dye does not show straightforward improvements to the complex photocatalytic behaviour depending on the configuration of the (two- or three-electrode) photoelectrochemical cell, type of the experiment and sample aging. The time constant for electron transport in BiVO4 electrodes (in the range of seconds, revealed by electrochemical impedance measurements) was found to correlate with the stable photocurrent of the cells. The femtosecond transient absorption studies confirm the negligible effects of RuP on the population of the photoexcited carriers in BiVO4. The transient absorption studies also show that the processes responsible for the differences in photocurrents of the modified BiVO4 samples occur on a time scale longer than the first nanoseconds., QC 20200706
