US10411156B2 Active App. US15/942406

Device with transparent and higher conductive regions in lateral cross section of semiconductor layer

A device including one or more layers with lateral regions configured to facilitate the transmission of radiation through the layer and lateral regions configured to facilitate current flow through the layer is provided. The layer can comprise a short period superlattice, which includes barriers alternating with wells. In this case, the barriers can include both transparent regions, which are configured to reduce an amount of radiation that is absorbed in the layer, and higher conductive regions, which are configured to keep the voltage drop across the layer within a desired range.

Heterostructure semiconductor device

A heterostructure semiconductor device that includes a composite layer between an active layer and a gate. The composite layer includes a strain matching layer and a barrier layer. The strain matching layer reduces the strain between the barrier layer and the active layer. The device can incorporate various additional layers as well as gate and/or contact configurations to obtain desired device performance characteristics.
