“…The lenghth of the former is influenced by the bridging-gap on the substrate 19 , and that of the latter is determined by the film thickness. As a result, the electrons and holes in the planar-type devices have to move much longer than those in the vertical-type ones to the electrodes 22 . On the other hand, numerous defects and extensive disorders in MAPbI 3 polycrystalline film antagonize the charge migration process.…”

Recently, the discovery of organometallic halide perovskites provides promising routes for fabricating optoelectronic devices with low cost and high performance. Previous experimental studies of MAPbI3 optoelectronic devices, such as photodetectors and solar cells, are normally based on polycrystalline films. In this work, a high-performance planar-type photodetector fabricated on the (100) facet of a MAPbI3 single crystal is proposed. We demonstrate that MAPbI3 photodetector based on single crystal can perform much better than that on polycrystalline-film counterpart. The low trap density of MAPbI3 single crystal accounts for the higher carrier mobility and longer carrier diffusion length, resulted in a significant performance increasement of MAPbI3 photodetector. Compared with similar planar-type photodetectors based on MAPbI3 polycrystalline film, our MAPbI3 single crystal photodetector showed excellent performance with good stability and durability, broader response spectrum to near-infrared region, about 102 times higher responsivity and EQE, and approximately 103 times faster response speed. These results may pave the way for exploiting high-performance perovskites photodetectors based on single crystal.

“…2 During the development of MBTs, a related device, the permeable-base transistor ͑PBT͒ was also developed, which differs from the MBT due to the existence of unintentionally existing pinholes or intentionally introduced grid structure in the base. 5 In the past decade, several organic materials were used to demonstrate several hybrid and all-organic vertical architecture transistors, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] including hybrid MBTs with the base made of conducting polymer blend instead of a metal. 5 In the past decade, several organic materials were used to demonstrate several hybrid and all-organic vertical architecture transistors, [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] including hybrid MBTs with the base made of conducting polymer blend instead of a metal.…”

“…The reaction with oxygen plasma in the TC device’s pentacene layer produced a derivative known as 6,13-pentacenequinone. The performance results for other thermally evaporated OTFTs are listed in Table 1 [ 55 , 57 , 58 , 59 , 60 ]. Note that the table lists only the average typical values relevant to this manuscript.…”

Review of the Common Deposition Methods of Thin-Film Pentacene, Its Derivatives, and Their Performance

et al. 2022

Pentacene is a well-known conjugated organic molecule with high mobility and a sensitive photo response. It is widely used in electronic devices, such as in organic thin-film transistors (OTFTs), organic light-emitting diodes (OLEDs), photodetectors, and smart sensors. With the development of flexible and wearable electronics, the deposition of good-quality pentacene films in large-scale organic electronics at the industrial level has drawn more research attention. Several methods are used to deposit pentacene thin films. The thermal evaporation technique is the most frequently used method for depositing thin films, as it has low contamination rates and a well-controlled deposition rate. Solution-processable methods such as spin coating, dip coating, and inkjet printing have also been widely studied because they enable large-scale deposition and low-cost fabrication of devices. This review summarizes the deposition principles and control parameters of each deposition method for pentacene and its derivatives. Each method is discussed in terms of experimentation and theory. Based on film quality and device performance, the review also provides a comparison of each method to provide recommendations for specific device applications.
