A tunnel junction is adjacent the p-type layer for converting the lateral current into hole current. In an embodiment of this form of the disclosure, the tunnel junction is as an n+/p+ (132, 131) junction oriented with the p+ (131) portion thereof adjacent the p-type layer. The lateral current can be electron current in the n+ layer (132) and/or electron current in a further layer of n-type material disposed over the tunnel junction.
