Efficient laser induced consolidation of nanoparticulate ZnO thin films with reduced thermal budget

Abstract

Layers of ZnO nanoparticles with thicknesses of about 40 nm were prepared on Si substrates. It was shown that UV laser irradiation is suitable for consolidation and significant densification of the ZnO particle layers under ambient conditions. Both experiments and simulations show that an underlying SiO 2 particle layer has a beneficial effect in inhibiting heat transfer towards the substrate and thus enables the application of temperature-sensitive carrier substrates like polymer foils despite the extremely high melting temperature of ZnO

Organophosphonates as anchoring agents onto metal oxide-based materials: synthesis and applications

“…Zinc oxide (ZnO) is a transparent piezoelectric metal oxide with potential applications in sensors, 71 light-emitting diodes 72 (LEDs), lasers, 73 transistors, and solar cells. 74 ZnO is a direct wide-gap semiconductor with specic properties including high electron mobility and strong luminescence.…”

Determination of the effective refractive index of nanoparticulate ITO layers

“…In these devices conductive ITO films are coated on the desired substrates by vacuum deposition methods [3][4][5]. Recently, alternative methods for ITO layer generation from nanoparticle suspensions have attracted considerable attention as a possible inexpensive alternative route for production of functional electronics [6][7][8][9][10]. If such materials are used for optoelectronic applications or laser processed, knowledge about their optical properties, especially their complex refractive index is needed.…”

Effect of Mn-doping Concentration on the Structural a Magnetic Properties of Sol-Gel Deposited ZnO Diluted Magnetic Semiconductor

“…Among II-VI host semiconductors, ZnO is a versatile and potential candidate 3 having a direct wide band gap (3.37 eV), large exciton-binding energy (60 meV), eco-friendly, high transparency, biocompatible and non-toxic.
