Enhancement of 2DEG effective mass in AlN/Al0.78Ga0.22N high electron mobility transistor structure determined by THz optical Hall effect
We report on the free charge carrier properties of a two-dimensional electron gas (2DEG) in an AlN/AlxGa1-xN high electron mobility transistor structure with a high aluminum content (x = 0.78). The 2DEG sheet density N s = (7.3 ± 0.7) × 10 12 cm-2, sheet mobility μ s = (270 ± 40) cm2/(Vs), sheet resistance R s = (3200 ± 500) ω / □, and effective mass m eff = (0.63 ± 0.04) m 0 at low temperatures (
Standardization of Antigen-Emulsion Preparations for the Induction of Autoimmune Disease Models
Autoimmune murine disease models are vital tools for identifying novel targets and finding better treatments for human diseases. Complete Freund’s adjuvant is commonly used to induce disease in autoimmune models, and the quality of the adjuvant/autoantigen emulsion is of critical importance in determining reproducibility. We have established an emulsification method using a standard homogenizer an
InP/InAsP Quantum Discs-in-Nanowire Array Photodetectors: Design, Fabrication and Optical Performance
This thesis focuses on processing and electro-optical investigations of two- and three-terminal photodetectors based on large arrays of around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. First, we investigated the optoelectronic behavior of two-terminal photodetectors under selective 980 nm excitation of the 20 axially embedded InAsP qu
Multi-modality Imaging Evaluation of a Rare and Complex Case of Single Ventricle Physiology; the important role of Cardiac MR
Congenital heart diseases (CHD) represent a major clinical and diagnostic challenge for correct abnormality identification and subsequent successful therapy; even more challenging is following-up patient health after multiple post-interventional corrections often required in complex cardio-vascular abnormalities. We describe a multi-modality imaging evaluation of a complex congenital cardio-vascul

Hydroxyl radical dynamics in a gliding arc discharge using high-speed PLIF imaging
Plasma discharges can be transient and randomly distributed where a few investigations have been carried out using laser-induced fluorescence to capture snapshots of plasma-produced radicals in the near vicinity of the discharge. Radical distribution dynamics, however, are challenging to study in situ with high spatial and temporal resolution to fully capture the interactions between the discharge
