2、 Patent any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEEE Standards documents are developed within IEEE Societies an
3、d Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessa
4、rily members of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of IEEE
5、 Standards documents is wholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see http:/standards.ieee.org/IPR/disclaimers.html for more information). IEC collaborates closely with IEEE in accordance with conditions determined by agreement be
6、tween the two organizations. 2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. The formal decisions of IEEE
7、on technical matters, once consensus within IEEE Societies and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards document is given by t
8、he IEEE Standards Association (IEEE-SA) Standards Board. 3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC/IEEE Pu
9、blications is accurate, IEC or IEEE cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications (including IEC/IEEE Publications) transparently
10、 to the maximum extent possible in their national and regional publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC and IEEE do not provide any attestation of conformity. Independent cert
11、ification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No li

Abstract: Recommended methods and standardized reporting practices for electrical characterization of printed and organic transistors are covered. Due to t
23、he nature of printed and organic electronics, significant measurement errors can be introduced if the electrical characterization design-of-experiment is not properly addressed. This standard describes the most common sources of measurement error, particularly for high-impedance electrical measureme
24、nts commonly required for printed and organic transistors. This standard also gives recommended practices in order to minimize and/or characterize the effect of measurement artifacts and other sources of error encountered while measuring printed and organic transistors.

26、ction This introduction is not part of IEEE Std 1620-2008, IEEE Standard for Test Methods for the Characterization of Organic Transistors and Materials. This standard covers recommended methods and standardized reporting practices for electrical characterization of organic transistors. Due to the na
27、ture of organic transistors, significant measurement errors can be introduced if not properly addressed. This standard describes the most common sources of measurement error and gives recommended practices in order to minimize and/or characterize the effect of each. Standard reporting practices are
28、included in order to minimize confusion in analyzing reported data. Disclosure of environmental conditions and sample size are included so that results can be appropriately assessed by the research community. These reporting practices also support repeatability of results so that new discoveries may
29、 be confirmed more efficiently. The practices in this standard were compiled from research and industry organizations developing organic transistor devices, materials, and manufacturing techniques. These practices were based on standard operating procedures utilized in laboratories worldwide. This s
30、tandard was initiated in 2002 to facilitate the evolution of organic transistors from the laboratory into a sustainable industry. Standardized characterization methods and reporting practices create a means of effective comparison of information and a foundation for manufacturing readiness. Notice t

Overview 1.1 Scope This standard describes a method for characteri
45、zing organic electronic devices, including measurement techniques, methods of reporting data, and the testing conditions during characterization. 1.2 Purpose The purpose of this standard is to provide a method for systematically characterizing organic transistors. These standards are intended to max
46、imize reproducibility of published results by providing a framework for testing organic devices, whose unique properties cause measurement issues not typically encountered with inorganic devices. This standard stresses disclosure of the procedures used to measure data and extract parameters so that
47、data quality may be easily assessed. This standard also sets guidelines for reporting data, so that information is clear and consistent throughout the research community and industry. 2 IEC 62860:2013(E) IEEE Std 1620-2008 Published by IEC under license from IEEE. 2008 IEEE.

48、 Electrical characterization overview 1.3.1 Testing apparatus Testing is performed using an electronic device test system with measurement sensitivity sufficient to give an accuracy of at least 0.1% (minimum sensitivity at or better than three orders of magnitude below expected signal level). For ex
49、ample, the smallest current through an organic transistor is often the gate leakage current. If gate leakage is approximately 1 pA (10g23712A), the instrument shall have a resolution of 1 fA (10g23715g36g12g3 g82g85g3 g86g80g68g79g79g72g85g17g3 g36g71g71g76g87g76g82g81g68g79g79g92g15g3 g71g88g72g3 g87g82g3 g87g75g72g3 g79g68g85g74g72g3 g11g33g20g3 g42g159g12g3 g76g80g83g72g71g68g81g70g72g86g3 g72g81g70g82g88g81g87g72g85g72g71g3 g76g81g3 g82g85g74g68g81g76g70g3devices, the input impedance of all elements of the test system shall be at l
