Crude silicon was readily available but difficult to purify due to its very high melting point and high reactivity. It was used in early detectors but did not give reliable performance. Progress was made when Karl Seiler collaborated with Paul Ludwig Günther a physical chemist working at Breslau for the Reich Aviation Ministry.
Yole proposes today a deep understanding of the whole supply chain related to GaAs material for smartphone’s appliion and its 3D sensing function. More than a comprehensive overview of the technology and market challenges at the GaAs substrate level, the strategy consulting & market research company proposes today a relevant collection of reports focused on the analysis at both device and

“It is relatively easy to grow one layer of graphene on silicon carbide. But it’s a greater challenge to grow large-area uniform graphene that consists of several layers on top of each other. We have now shown that it is possible to grow uniform graphene that consists of up to four layers in a controlled manner”, says Jianwu Sun, of the Department of Physics, Chemistry and Biology at LiU.

Silicon carbide (SiC) is another alternative to silicon, but GaN generally has more attractive fundamental material properties. Current GaN devices are made on hybrid substrates: thin layers of GaN on silicon or silicon carbide, creating GaN-on-Si or GaN-on-SiC high-electron-mobility transistor (HEMT) structures ( Figure 3 ).
