“…During the 1970s and 80s, this initial discovery was followed by the creation of myriads of small molecule and polymeric conductors and semiconductors, culminating in the demonstration of multiple optoelectronic device platforms including organic solar cells, 24 field effect transistors 25 and ultimately photodetectors. 26 The potential for organic photodetectors (OPDs) to achieve filter-less narrowband colour sensing was recognised early in the first homojunctions and linear heterojunctions.…”

“…Inspired by the Nobel prize awarded work of Alan Heeger, Hideki Shirakawa, and Alan MacDiarmid in the 1970s, many researchers focused on conjugated polymers which exhibit good conductivity if prepared properly [32]. In the 1980s, organic heterojunctions [33] and organic thin film transistors [34][35][36] have been demonstrated. The final breakthrough happened after the realization of high efficiency electroluminescence from organic light emitting diodes built both from polymers [37,38] and oligomers [39,40].…”

Abstract. Thin films formed from small molecules rapidly gain importance in different technological fields. To explain their growth, methods developed for zero-dimensional atoms as the film forming particles are applied. However, in organic thin film growth the dimensionality of the building blocks comes into play. Using the special case of the model molecule para-Sexiphenyl, we will emphasize the challenges that arise from the anisotropic and one-dimensional nature of building blocks. Differences or common features with other rodlike molecules will be discussed. The typical morphologies encountered for this group of molecules and the relevant growth modes will be investigated. Special attention is given to the transition between flat lying and upright orientation of the building blocks during nucleation. We will further discuss methods to control the molecular orientation and describe the involved diffusion processes qualitatively and quantitatively.

“…Indeed, electrically conductive organic materials are an alternative to inorganic conductors or semi conductors. They are currently used in organic photovoltaic panels [1], organic light emitting diodes (OLEDs) [2] and organic field effect transistors [3]. However, one of their drawbacks is their short lifetime, which is due to premature degradation and EPJ Web of Conferences their weak stability when working at increasing temperature [4].…”

Abstract. Organic semiconductors for opto-electronic devices show several defects which can be enhanced while increasing the operating temperature. Their thermal management and especially the reduction of their temperature are of great interest. For the heat transfer study, one has to measure the thermal conductivity of thin film organic materials. However the major difficulty for this measurement is the very low thickness of the films which needs the use of very specific techniques. In our work, the 3-omega and photothermal radiometric methods were used to measure the thermal conductivity of thin film organic semiconducting material (Alq3). The measurements were performed as function of the thin film thickness from 45 to 785 nm and also of its temperature from 80 to 350 K. With the 3 omega method, a thermal conductivity value of 0.066 W.m −1 K −1 was obtained for Alq3 thin film of 200 nm at room temperature, in close agreement with the photothermal value. Both techniques appear to be complementary: the 3 omega method is easier to implement for large temperature range and small thicknesses down to a few tens of nanometers whereas the photothermal method is more suitable for thicknesses over 200nm since it provides additional information such as the thin film volumetric heat capacity.
