…autonomous technologies and robotics. Semiconductors underpin the rise of solar. Solar semiconductors harness the photovoltaic effect, transforming diffuse sunlight into a direct current, which further semiconductors can invert into an…
…the ‘price’ is equally ineffable. A 200mm SiC wafer might cost $1,500 to produce and weigh 50-grams, yielding an effective cost of $30M/ton of SiC contained, or $10M/ton of SiC…
…the conductivity of semiconductors, in spreadsheet format, from first principles, as a useful reference file for our broader modelling of semiconductors, from solar panels to electric vehicles. The basic formula…
Semiconductors underpin solar panels, electric vehicles and electronics. Hence this 20-page note aims to explain semiconductor physics from first principles: their conductivity and resistance, their use in devices, plus implications…
…digital switches made of semiconductor materials, which allow one circuit to control another. Our overview of semiconductors explains how a transistor works, from first principles, by depicting a bipolar junction…
…charted the company’s revenues, employee count, market share in MOSFETs, market share in SiC devices, market share in SiC materials, total estimated revenues from SiC and proportionate exposure to SiC….
…(SiC) is a fundamentally better semiconductor for power-electronic applications, yielding 1-10% efficiency improvements (page 5). Why is SiC “better”? The answer stems from material properties, including 100x lower on-resistance, 10x…
…to make 70% of LEDs globally, but also for wide-bandgap semiconductors, such as SiC and GaN, the market leader is a publicly listed German specialist, with 70% market share. In…
…analysis on the bandgap, the next chart below shows that our 43-44% conversion limit holds for any semiconductors with a bandgap of 1.1-1.35eV, more of a plateau than a sharp…
…up to 13% higher range than today’s inverters, especially for use in EV powertrains; but also in wind, solar, batteries and fast-chargers. It is based on SiC semiconductors. This Hillcrest…
