Assessment of an MnCe-GAC Treatment Process for Tetramethylammonium-Contaminated Wastewater from Optoelectronic Industries

Applied Sciences, 2019
Nitrogen-containing wastewater is an important issue in optoelectronic and semiconductor industries. Wastewater containing nitrogen compounds such as ammonium, monoethanolamine (MEA), and tetramethylammonium hydroxide (TMAH) must be properly treated due ...

Revealing the Role of Sidewall Orientation in Wet Chemical Etching of GaN-Based Ultraviolet Light-Emitting Diodes

Nanomaterials, 2019
We demonstrated that the tetramethylammonium hydroxide (TMAH) solution possesses different etching abilities to the chip sidewalls with different orientations because the orientation of chip sidewall determines the exposed crystallographic plane of ...

Dual-Surface Modification of AlGaN/GaN HEMTs Using TMAH and Piranha Solutions for Enhancing Current and 1/f-Noise Characteristics

IEEE Journal of the Electron Devices Society, 2018
We demonstrated dual-surface modification of GaN/AlGaN/GaN high-electron mobility transistors using tetramethylammonium hydroxide (TMAH) and piranha solutions prior to gate metallization.

An alternative method for the determination of siloxane activities toward basic equilibration catalysts [PDF]

Journal of the Serbian Chemical Society, 2005
The method used is based on the well-known fact that siloxane equilibrates once formed, do not change their compositions unless some siloxane compound is added, in which case new equilibrium compositions appear.

Effective suppression of interface states in recessed-gate MIS-HEMTs by TMAH wet etching

Applied Physics Express, 2023
The effect of tetramethylammonium hydroxide (TMAH) treatment prior to gate dielectric deposition on the performance of recessed-gate AlGaN/GaN metal-insulator-semiconductor high electron mobility transistors (MIS-HEMTs) was investigated.

Characterization of m-GaN and a-GaN Crystallographic Planes after Being Chemically Etched in TMAH Solution

Energies, 2021
This paper proposes a new technique to engineer the Fin channel in vertical GaN FinFET toward a straight and smooth channel sidewall. Consequently, the GaN wet etching in the TMAH solution is detailed; we found that the m-GaN plane has lower surface ...
