Heterojunction diode current this section is very similar to the one discussing currents across a homojunction.
Heterojunction diode pdf. In this handout we will consider four different kinds of commonly encountered heterostructures. Georgia tech ece 3080 dr. Just as for the homojunction we find that current in a n junction can only exist if there is recombination orp.
Two dimensional 2d materials and iiiv compound semiconductors are two representative materials providing excellent heterojunction platforms for the fabrication of heterostructure devices. The hetero p n junction the heterojunction n diode is in principle very similar to a homojunction. Chapter 2 semiconductor heterostructures 21 introduction most interesting semiconductor devices usually have two or more different kinds of semiconductors.
In this paper we report enhanced breakdown characteristics of ptbatio3al058ga042n lateral heterojunction diodes compared to ptal058ga042n schottky diodes. Alan doolittle lecture 11b schottky diodes heterojunctions and ndr diodes reading. The main problemp that needs to be tackled is he effect of the bandgap discontinuities and the different materialt parameters which make the actual calculations more complex even though the n diode p concepts need almost no changing.
Semiconductor heterostructures have enabled numerous applications in diodes photodetectors junction field effect transistors and memory devices. A pn heterojunction diode b nn heterojunctions c pp heterojunctions.
