Abstract
A transistor comprises a substrate comprising a Group III/V compound semiconductor material having a cubic crystalline phase structure positioned on a hexagonal crystalline phase layer having a first region and a second region, the cubic crystalline phase structure being positioned between the first region and the second region of the hexagonal crystalline phase layer. A source region and a drain region are both positioned in the Group III/V compound semiconductor material. A channel region is in the Group III/V compound semiconductor material. A gate is over the channel region. An optional backside contact can also be formed. A source contact and electrode are positioned to provide electrical contact to the source region. A drain contact and electrode are positioned to provide electrical contact to the drain region. Methods of forming transistors are also disclosed.
