Photothermal Deflection Spectroscopy (PDS) is used to study the sub-bandgap absorption of hexagonal gallium nitride (GaN) in the energy range from 0.6 to 3.8 eV. Auto-, n- and p-doped GaN layers deposited by chemical vapour deposition from organometallic precursors (MOCVD) or electron cyclotron...
不过你说的 sub-bandgap absorption目测像是指能量小于带隙的吸收，和子能带看似没有关系。。。
While the exponential contribution can be reliably assigned to disorder effects, the SBG EQE Gaussian profile can be due to charge-transfer absorption between P3HT and PCBM or due to absorption of PCBM at the interface or in the polymer-rich phase. 展开 关键词:...
In comparison, the PLM processed ZnTe:O diode exhibits a distinguished band of spectral response centered at 1.8 eV, which exactly has the same spectral overlapping with the enhanced absorption in Fig. 6(a) and IB emission in Fig. 5(a). As expected, the high electron capture cross-...
The parabolic Tauc edge as well as the exponential Urbach tail are identified in the absorption spectrum. The Tauc edge supports that the density of states at the bottom of conduction band is proportional to the square root of energy. The Urbach edge is attributed to interband transition caused...
Another aspect not considered in PM-OPDs concerns photomultiplication in the extended charge-transfer (CT) state absorption region. With the aid of a Fabry-Perot microcavity, this rather weak absorption region has been used in NIR narrowband organic photodetectors (CT-OPDs)36,37,38. Such narrowban...

AbsorptionNear-Infrared WavelengthsSilicon Photonics has generated an increasing interest in recent years both for optical telecommunications and for optical interconnects in microelectronic circuits. Although silicon photodiodes are excellent detectors at visible wavelengths, due to its band-gap the development...
For Fe-containing CuGaS2 films, distinct sub-gap absorption bands at 1·2eV and 1·9eV are detected, which increase in prominence with increasing Fe content. On the other hand, the solar cell parameters were found to deteriorate with increasing iron content, indicating an increase in non-...
