Scientists have advanced gallium nitride (GaN)-on-silicon transistor technology by optimizing the composition of the semiconductor layers that make up the device. The team created the high electron ...

Gallium-nitride (GaN) is becoming increasingly attractive in power electronics because the low switching losses of GaN enable high-frequency operation, which reduces the size of passive components ...

This year, several companies are expected to bring 600/650 V Gallium Nitride (GaN) power transistors to market. Almost all will be normally-on (depletion mode) transistors connected in a cascode ...

Imec claims a new benchmark for mobile RF transistor performance. The approach, based on a gallium nitride (GaN) metal-oxide semiconductor high-electron-mobility transistor (MOSHEMT) on silicon (Si), ...

LONDON — Oki Electric Industry Co., Ltd. has developed a GaN-HEMT power transistor on silicon substrates that it says dramatically improves amplifying performance compared with other available power ...

In a recent research paper, Graphenea demonstrated the use of graphene as an intermediary layer to grow GaN-on-silicon devices. Semiconductors fabricated from third-group periodic table elements and ...

Communication satellites and flying antenna platforms can contribute to the comprehensive and resilient operation of global mobile networks of the fifth and sixth generation (5G, 6G). However, as ...

A new method to fit together layers of semiconductors as thin as a few nanometers has resulted in not only a scientific discovery but also a new type of transistor for high-power electronic devices. A ...

While 5G applications are proliferating everywhere, the industry continues to face a myriad of challenges implementing the technology. One of them has been the performance limitations of ...

Circuits built with discrete GaN components may get the job done, but fully integrated GaN circuits remain the ultimate goal because they would offer many of the same advantages as integrated silicon ...
