Diamond waveguides fabricated by reactive ion etching

open access: yesOptics Express, 2008
We demonstrate for the first time the feasibility of all-diamond integrated optic devices over large areas using a combination of photolithography, reactive ion etching (RIE) and focused ion beam (FIB) techniques. We confirm the viability of this scalable process by demonstrating guidance in a two-moded ridge waveguide in type 1b single crystal diamond.

Development of Reactive-Ion Etching for ZnO-Based Nanodevices [PDF]

open access: yesIEEE Transactions on Nanotechnology, 2011
We report on the systematic studies of reactive-ion etching (RIE) conditions for zinc oxide (ZnO) films with methane and hydrogen gases. The etching conditions were optimized to ensure high selectivity of ZnO to poly(methyl methacrylate) (PMMA), which is commonly used as an etching mask in nanolithography.

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Novel Tailoring of Ternary ZnS‐MXene‐TiO2 Nanocomposite Heterojunction and Its Tunable Electrochemical Properties With Enhanced Photocatalytic Degradation

open access: yesAdvanced Engineering Materials, EarlyView.
ZnS‐MXene‐TiO2 nanocomposite heterojunction for photocatalytic decomposition of this methylene blue dye (MB) greatly improves light absorption, charge separation, and active site area. Two‐dimensional MXene forms nanocomposites by easily combining them with 0D (quantum dots), 1D (tube and wire), 2D (plane and sheet), and 3D (particle and lamellar ...

Electronic cooling of a submicron-sized metallic beam [PDF]

open access: yes, 2008
We demonstrate electronic cooling of a suspended AuPd island using superconductor-insulator-normal metal tunnel junctions. This was achieved by developing a simple fabrication method for reliably releasing narrow submicron sized metal beams.

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Formation of distinctive structures of GaN by inductively-coupled-plasma and reactive ion etching under optimized chemical etching conditions

open access: yesAIP Advances, 2017
We focused on inductively coupled plasma and reactive ion etching (ICP–RIE) for etching GaN and tried to fabricate distinctive GaN structures under optimized chemical etching conditions.

The role of fluorine-containing ultra-thin layer in controlling boron thermal diffusion into silicon

open access: yesJournal of Telecommunications and Information Technology, 2023
We have investigated the influence of silicon dioxide reactive ion etching (RIE) parameters on the composition of the polymer layer that is formed during this process on top of the etched layer, and finally, the role of this layer in high- temperature ...

Nd-doped aluminum oxide integrated amplifiers at 880 nm, 1060 nm, and 1330 nm [PDF]

open access: yes, 2010
Neodymium-doped Al2O3 layers were deposited on thermally oxidized Si substrates and channel waveguides were patterned using reactive-ion etching. Internal net gain on the Nd3+ transitions at 880, 1064, and 1330 nm was investigated,\ud yielding a maximum ...
