%X Today, most of electronic devices are based on heterostructures made by molecular beam epitaxy. The impact of van der Waals heterostructures made of 2D materials, already significant at the academic level [1], could generate a technological breakthrough in this field of electronics. Indeed, due to the weak van der Waals interlayer interactions, several materials can be assembled with a precise control of their thicknesses or their twist angles and with high quality interfaces.Recently, hybrid van der waals heterostructures, obtained by combining 2D materials and self-organized organic layers has been developed [2]. Such approach is promising to push further the versatility in terms of materials and thus a wide range of properties are expected.In this poster, we present recent results obtained on field effect transistor based on an hybrid van der Waals heterostructure made of molybdenum disulfide (MoS2) for the inorganic part and quinoidal zwitterions (QZ) for the organic part. The organic layer deposition is achieved under high vacuum, on top of the MoS2 channel of the transistor and the evolution of the transfer characteristic of the transistor is measured in situ.We observed a n-type doping and an increase of the charge carrier density of two orders of magnitudes which is comparable to the doping obtained with optimized charge transfer molecules [3][4]. These results which demonstrate the high compatibility of the QZ with MoS2 open the way for future investigations on functionalized hybrid QZ-2D materials heterostructures[1] A. K. Geim & I. V.
