But a large difference in the bandgap would be a blockage in extraction of photo generated carriers from a heterojunction.
32.
These results demonstrate that graphene / Si heterojunction with interfacial oxide is promising for the development of high detectivity photodetectors.
33.
Planar heterojunction perovskite solar cells can be manufactured in simplified device architectures ( without complex nanostructures ) using only vapor deposition.
34.
Originally, MMICs used High Electron Mobility Transistors ( HEMTs ), Pseudomorphic HEMTs and Heterojunction Bipolar Transistors have become common.
35.
Unlike conventional crystalline silicon cells based on a homojunction, the structure of CIGS cells is a more complex heterojunction system.
36.
It was used with indium gallium arsenide to make a record breaking pseudomorphic heterojunction bipolar transistor that could operate at 604 GHz.
37.
When a heterojunction is formed by two different semiconductors, a quantum well can be fabricated due to difference in band structure.
38.
In 2008, scientists were able to create a nanostructured lamellar structure that provides an ideal design for bulk heterojunction solar cells.
39.
A simple heterojunction design evolved in which p-type CdTe was matched with n-type cadmium sulfide ( CdS ).
40.
The presence of a heterojunction offset reduces the collection efficiency of the solar cell and may contribute to low fill-factor.
