We demonstrate this architecture using a light emitting organic field-effect transistor (LEOFET) operated at a dual-transduction mode, as a proof-of-concept.
The microcavity structure consists of an organic light emitting diode with field-effect electron transport inserted in a high-quality factor double distributed Bragg reflector.
Light emitting field effect transistors (LEFETs) are emerging as a multi-functional class of optoelectronic devices.
The organic semiconductor para-hexaphenylene (p 6P) can self-assemble into crystalline nanofibers structures that emit polarized, blue light upon UV excitation [20], and it has been shown to work as light-emitting material in organic light-emitting field-effect transistors (OLEFETs) [21].

Investigation of a bulk heterostructure of a thienylene derivative and PTCDI-C13H27 results in a light-emitting field-effect transistor.
One-dimensional zinc oxide (ZnO) nanostructures have been the subject of intense research in the past few years due to their unique properties and thus potential wide-ranging applications in a variety of fields such as solar cells [1 3], sensors [4, 5], short-wavelength light emitting and field effect devices [6, 7], Schottky diodes [8, 9], and coating materials [10, 11].
The growth of semiconductor nanowires (NWs) has recently opened new paths to silicon integration in device families such as light emitting diodes, field effect transistors (FET), high-efficiency photovoltaics, or high-responsivity photodetectors [1 3].
The ability to control the architectures of these ensembles is thus essential for optimizing the properties of conjugated materials for use in electronic devices (light emitting diodes, field effect transistors, solar cells, …) and is primordial for potential technological applications in nanoelectronics.
The interest of both fundamental and applied science was mainly driven by the goal to understand and improve the properties of materials used for organic electronics (e.g., light emitting diodes, field effect transistors and solar cells) and to establish novel systems for optical applications (e.g., waveguiding and lasing).
