The ‘field-effect’ underlies the operation of most conventional electronic devices. However, effective control and implementation of the field-effect in semiconductor devices are limited due to screening of the electric-field by conducting electrodes. Thus far, the electronic devices have necessarily been designed to avoid or minimize the electricfield screening effect. As an alternative approach to this, a new type of conducting electrodes which would be transparent to both visible light and electric-field while being electrically conductive have been developed. Here, we define these electrodes as ‘electric-field transparent electrodes’ and provide a review on related work. Particular attention is paid to the material selection and design strategies to enhance the electric-field transparency of the electrodes while maintaining good electrical conductivity and optical transparency. We then introduce potential applications of the electric-field transparent electrodes in electronic and optoelectronic devices.
