Diamond device with high breakdown voltage Researchers from the University of Illinois at Urbana-Champaign developed diamond p-type lateral Schottky barrier diodes they say have the highest breakdown voltage and lowest leakage current compared to previous diamond devices. The diamond device can sustain high voltage, approximately 5 kV, although the voltage was limited by setup of measurement a... » read more

Stretchy semiconductors Researchers from Pennsylvania State University, University of Houston, Southeast University, and Northwestern University are working towards fully flexible electronics. “Such technology requires stretchy elastic semiconductors, the core material needed to enable integrated circuits that are critical to the technology enabling our computers, phones and so much more,... » read more

Excess noise in high-current diamond diodes
By Technical Paper Link - 17 Feb, 2022 - Comments: 0

Abstract "We report the results of an investigation of low-frequency excess noise in high-current diamond diodes. It was found that the electronic excess noise of the diamond diodes is dominated by the 1/f and generation-recombination noise, which reveals itself as Lorentzian spectral features (f is the frequency). The generation-recombination bulges are characteristic of diamond diodes with l... » read more

Fabrication of GaN/Diamond Heterointerface and Interfacial Chemical Bonding State for Highly Efficient Device Design
By Technical Paper Link - 10 Jan, 2022 - Comments: 0

Abstract "The direct integration of gallium nitride (GaN) and diamond holds much promise for high-power devices. However, it is a big challenge to grow GaN on diamond due to the large lattice and thermal-expansion coefficient mismatch between GaN and diamond. In this work, the fabrication of a GaN/diamond heterointerface is successfully achieved by a surface activated bonding (SAB) method at r... » read more

A ring of 18 carbon atoms Scientists at IBM Research – Zurich and Oxford University write about allotropes of carbon – the many versions of atomic carbon formations, such as diamonds and graphite. “Carbon, one of the most abundant elements in the universe, can exist in different forms - called allotropes - giving it completely different properties from color to shape to hardness. For... » read more

Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more

Diamond metrology The U.S. Department of Energy’s Ames Laboratory is building a new instrument called an optical magnetometer. The system will help researchers understand the properties of new magnetic nanomaterials. The system, dubbed the NV-magnetoscope, makes use of the properties of nitrogen-vacancy (NV) centers in diamonds. According to researchers, diamonds have a flaw, or imperfect... » read more

5 Technologies To Watch

Diamond shock waves For years, the industry has been exploring the use of diamonds for electronics applications. Diamonds could be used to reduce heat in electronic systems. In addition, diamond FETs are also intriguing. Diamond has a wide bandgap (5.45 eV), a high breakdown field (10MV/cm), and high thermal conductivity (22W/cmK). But it could take years before diamond FETs reach the mains... » read more
