Organic diode rectifier have attracted a lot of attention recently for RF energy harvesting, and much effort has been applied toward extending the ultra-high frequency range [1-2]. An important parameter that should be considered for diodes used in RF rectifier is the turn on voltage, which should be low to overcome the problem of the low voltage generated and power extracted from energy harvesting. In this work, we focused on pentacene organic rectifier with high rectification ratio and low threshold voltage obtained by tuning the work function of gold with a self-assembled monolayer of PFBT and optimizing the thickness of the organic layer. We demonstrate a high rectification ratio up to 107 and a very low turn on voltage as low as 20 mV. Flexible rectifier diode have been also fabricated in release paper WO84, high rectification ratio of 106 was obtained even after bending of the device. The pentacene based rectifier diodes were also demonstrated to operate at more than 1GHz. This provides a great potential for fabricating high-performance organic flexible diodes and opens the way for the development of high frequency response using organic materials. References [1] D.

有机二极管整流器近年来在射频能量收集方面受到了广泛的关注，并在超高频范围的扩展方面进行了大量的研究[1-2]。射频整流器中使用的二极管应该考虑的一个重要参数是导通电压，它应该是低的，以克服从能量收集中产生的低电压和功率提取的问题。本文主要研究了利用自组装单层PFBT调节金的功函数并优化有机层厚度，从而获得具有高整流比和低阈值电压的并五苯有机整流器。我们展示了高达107的高整流比和低至20 mV的极低导通电压。在WO84脱模纸上制备了柔性整流二极管，器件弯曲后仍能获得106的高整流比。并五苯整流二极管的工作频率也超过1GHz。这为制造高性能有机柔性二极管提供了巨大的潜力，并为利用有机材料开发高频响应开辟了道路。参考文献[j] m . et al .， vol . 23, 644-648(2011)。[2] C-mo。《电子学报》。物质学报，2,1500282(2016)。

We present the utilization of inorganic, organic, and hybrid (perovskite) thin film photodetectors in (bio)chemical sensing where OLEDs are used as the excitation source in compact devices. The sensitivity and feasible operational mode, whether monitoring the effect of the analyte concentration on the photoluminescence intensity or decay time following an OLED pulse will be discussed. While monitoring the PL decay time is the preferred operational mode, charge trapping and other defects impede the photodetectors’ response time, limiting the analysis dynamic range. Analytes tested include oxygen, glucose, lactate, and ethanol. Examples of all organic sensors for these analytes will be presented. The use of thin film photodetectors in on-chip (integrated all-organic) spectrometers will also be shown.

Organic-based electrochemical metallization memory (ECM) has been paid much attention for non-volatile memory devices owing to high integration and mechanical flexibility. In such ECM systems, the formation of conductive filaments (CFs) is typically composed of two activation steps: i) the electrochemical redox reactions at an interface between an electrode and an electrolyte and ii) the migration of the cations of metal across the electrolyte. Accordingly, the overall electrical performance of the ECM device is primarily governed by the kinetics of the two steps. However, in the ECM devices using organic electrolytes, a rather compete picture of the resistive switching during the ion-migration process has not been described so far since filamentary paths are barely observable. In this work, we investigated how the resistive switching depends on the ion-migration properties including the drift velocity and the migration path in the organic ECM device. Two types of polymer electrolytes, having different molecular weights, were used for the control of the ion drift velocity. The topography of ion-migration paths was modified by the deposition rate of metal for the top electrode. The formation and the retention of the CFs depend critically on the ion mobility of the polymer electrolyte and the topography of the ion-migration paths as well. These results will provide a useful guideline for constructing high- performance ECM storage systems based on organic materials. This work was supported by the Brain Korea 21 Plus Project in 2018.
有机基电化学金属化存储器(ECM)因其集成度高、机械柔韧性好等优点，在非易失性存储器件中受到广泛关注。在这样的ECM系统中，导电细丝(CFs)的形成通常由两个激活步骤组成:i)电极和电解质界面上的电化学氧化还原反应和ii)金属阳离子在电解质上的迁移。因此，ECM装置的整体电性能主要由这两个步骤的动力学决定。然而，在使用有机电解质的ECM器件中，由于纤维路径几乎无法观察到，因此到目前为止还没有描述离子迁移过程中电阻开关的相当竞争的画面。在这项工作中，我们研究了有机ECM器件中的电阻开关如何依赖于离子迁移特性，包括漂移速度和迁移路径。采用两种分子量不同的聚合物电解质来控制离子漂移速度。离子迁移路径的形貌受顶部电极金属沉积速率的影响。CFs的形成和保留主要取决于聚合物电解质的离子迁移率和离子迁移路径的形貌。这些结果将为构建基于有机材料的高性能ECM存储系统提供有益的指导。这项工作在2018年得到了Brain Korea 21 +项目的支持。

Organic photodiodes (OPDs) have in recent years reached a level of performance comparable to their inorganic counterparts. Using additives like PMMA, we were able to tune the transparency and viscosity of a P3HT:PCBM photoactive blend while at the same time achieving a two-fold enhancement of the detection speed. Furthermore, we have developed approaches towards the digital realization of image sensors using aerosol jet printing and a direct-printed patterning technique utilizing the self organization of functional inks. These techniques allow for a reproducible deposition of multilayer devices with high registration accuracies and feature sizes down to a few microns. We present a comprehensive electrical and optical characterization of these printed image sensors. The devices exhibit specific detectivities of >1E12 Jones over a broad wavelength range (400-750 nm) and maximum responsivities of 0.25 A/W. An entirely printed matrix image sensor composing of 256 individual pixels with an individual active area of ≈250 μm × 300 μm was fabricated.
