We call this phenomenon a heterojunction effect, which has been well demonstrated in OFETs and OPVs exhibiting highly efficient device performance.

In this case, the positive and negative charges are accumulated on the P-type and N-type sides, respectively, of the organic semiconductors to form the space charge region. We call this phenomenon a heterojunction effect, which has been well demonstrated in OFETs and OPVs exhibiting highly efficient device performance.
Therefore, our research demonstrates that the presence of a ferroelectric field can significantly improve the weak light detection performance of BaTiO 3 /GaN heterojunction photodetectors. At the same time, the coupling of pyroelectric current and photoelectric current synergistically enhances the sensitivity of the photodetector.
Clearly, in all the tested materials, HAT-CN/m-MTDATA heterojunction shows the best symmetry current property as well as the largest current density at the same bias. This indicates that m-MTDATA/HAT-CN organic heterojunction should possess the best charge generation efficiency than the others.
Differently, device 2 and device 3 with heterojunction exhibit a gradual increase of capacitance with voltage, and the turn-on voltage is reduced in device 3 due to the introduction of LiF and MoO3interfacial layers on the both sides of heterojunction.
However, the accumulation of heterojunction is completely different. In this case, the positive and negative charges are accumulated on the P-type and N-type sides, respectively, of the organic semiconductors to form the space charge region.
The most familiar heterojunction type in inorganic semiconductors is the depletion mode. In this type of heterojunction, a depletion junction is formed on either side of the heterojunction interface, namely the positive charges are accumulated on the N-type side and the negative charges are accumulated on the P-type side in the depletion region.
