  "account": "Köln – Siliziumkarbid semiconductors are considered key technology for powerful yet efficient electric vehicles. Unlike fast computing chips, their purpose is to switch large electrical powers with minimal losses. Crucial components in the inverter that converts direct current from the battery into the alternating current required by the electric motor, these inconspicuous parts determine how much power reaches the wheels and how much is lost as heat. Siliciumcarbid, or SiC for short, is a compound of silicon and carbon. While it also finds use in sandpaper or high-performance ceramics, it can be processed into semiconductor components in a manner similar to pure silicon. Its crucial advantage is the so-called wide band gap. Simplified, this describes the amount of energy needed to make electrons movable and thus enable a current flow. While silicon has a band gap of around 1.1 electron volts, SiC boasts a band gap of about 3.3 electron volts. As a result, silicon carbide can withstand much higher electrical field strengths and temperatures. Consequently, SiC components can be thinner and endure high voltages without short-circuiting. Simultaneously, SiC conducts heat more effectively than silicon.",
