Claim 9:
10. A method for fabricating a transistor comprising:
depositing a channel layer directly on a top of a substrate;
depositing a barrier layer on a top of the channel layer;
inserting a contact proximate with the barrier layer;
growing epitaxially a single-crystal lateral layer on top of at least a portion of the barrier layer whereby the lateral layer is operative to dissipate heat from the contact
and wherein prior to epitaxially growing the single-crystal lateral layer, providing an etch stop layer on a top of a portion of the barrier layer; and
providing a sacrificial layer on a top of the etch stop layer, wherein a portion of the contact is on top of the barrier layer and the etch stop layer.
