The electroluminescent (EL) characteristics and mechanism of device performance variation without and with different PHJs (herein including C60/CuPc, CuPc/C60 and CuPc) were systematically investigated in red, green and blue OLEDs.
In order to clearly understand the working mechanism of devices, the energy band diagrams are displayed in Fig. 4 (the inset in the figure shows the location of cutline).
This model has been used to verify the proper operation of the device in a prototype application and to identify the loss mechanisms of the device in the design stage.
The conducting and carrier transport mechanisms of the device were studied by using different theoretical models of organic electronics, and the electrical conduction of the device measured in air for the ON state was very different from that of the device measured in low oxygen concentrations.
Based on our previous investigations [13], we propose a conceptual design of nanotube-based memory cells in this paper and study the mechanisms of this device as static random access memory (SRAM) and dynamic random access memory (DRAM).
In order to elucidate the conduction mechanisms of the device, the I-V curve is plotted in the double-logarithmic mode, both the positive and negative bias regions, as shown in Figure 8a,b, respectively.
Herein, we review the progress in organometal halide perovskite photodetectors for the past few years, focusing on their key figure-of-merit features and operation mechanisms of different device structures.
The recombination mechanisms of the device that were discovered through the analysis of the photocurrent was observed to be mostly dominated by the trap-assisted recombination at high light powers.
As a result, a comprehensive review concerning probe-based storage devices is urgently required so as to reveal the physical mechanisms of these devices, and thus to ignite the research enthusiasm to further mitigate their respective storage performances.
