GaN Substrates (Bulk, Non-Polar)

Kyma's non-polar bulk GaN substrates include both a-plane and m-plane substrates which are sliced from GaN boules and can be prepared with on-axis orientation or can be intentionally misoriented, depending on customer requirements.

Typical properties of Kyma's non-polar GaN substrates are shown in the table below:
