AlN/GaN double-barrier resonant tunneling diodes RTDs were grown by metal-organic chemical vapor deposition on sapphire. RTDs were fabricated via standard processing steps. RTDs demonstrate a clear negative differential resistance NDR at room temperature RT . The NDR was observed around 4.7 V with a peak current density of 59 kA /cm2 and a peak-to-valley ratio of 1.6 at RT. Dislocation-free mat...

Ultrahigh-speed circuit applications of resonant-tunneling diodes (RTDs) have been developed. The key points are the utilization of the edge-triggered and latching properties arising from negative differential resistance of the RTD, and the combination of RTDs and high electron mobility transistors (HEMTs). High-speed and low power operation of various flip-flop (FF) circuits monolithically int...

Al(Ga)N/GaN resonant tunneling diodes (RTDs) are grown by metal-organic chemical vapor deposition. The effects of material quality on room temperature negative differential resistance (NDR) behaviour of RTDs are investigated by growing the RTD structure on AlN, GaN, and lateral epitaxial overgrowth GaN templates. This reveals that NDR characteristics of RTDs are very sensitive to material quali...

This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...

INTRODUCTION AND AIMS The ready-to-drink (RTD) market is growing rapidly, and this product category has been shown to be particularly appealing to young drinkers. The purpose of this study was to identify and describe the range and availability of RTDs available in New South Wales (NSW) (including metropolitan, regional and rural areas), with a particular focus on the variations in alcohol cont...

The negative differential resistance (NDR) of resonant tunneling diodes (RTDs) enables their use in fast-switching applications and logic circuit designs. So far, RTDs have been realized in Si/SiGe or IIIV compound material systems. However, various emerging devices have been proposed and studied in the past two decades. Recently, graphene nanoribbons (GNRs) have attracted much attention as the...

Rhesus macaque theta-defensins (RTDs) are unique macrocyclic antimicrobial peptides. The three RTDs (RTD 1-3), isolated from macaque leukocytes, have broad-spectrum antimicrobial activities in vitro and share certain structural features with acyclic porcine protegrins, which are microbicidal peptides of the cathelicidin family. To understand the structural features that confer the respective cy...

The ability to use resonant tunneling diodes (RTDs) as both transmitters and receivers is an emerging topic, especially with regards to wireless communications. Successful data transmission has been achieved using electronic RTDs with carrier frequencies exceeding 0.3 THz. Specific optical-based RTDs, which act as photodetectors, have been developed by adjusting the device structure to include ...
