• , 350 and 400 °C. On the other hand, oleic acid is a green organic ligand, which has been successfully used in preparing a great variety of colloidal materials [15][25][26], including CdTe quantum dots [27][28][29]. This work presents our early results on the elaboration of CdTe-based inks for potential

• type CuInSe2 in the current literature [15][16][17]. It has to be mentioned that the morphologies accessible by the liquid precursor route are not restricted to only Q1D nanostructures. Such stable ‘inks’ can also find application in printable photovoltaics or film deposition onto various standard

• or modify previously deposited films [5][6]. In the case of DPN, the AFM probe can be used to write a wide range of molecular inks with resolutions down to 15 nm [3][7][8]. However, in conventional DPN writing depends on the intrinsic fluidity of the ink molecules or on the creation of ink fluidity

• using solvents [9]. Unfortunately, inks and solvents that have sufficient intrinsic fluidity for DPN evaporate quickly in vacuum. This paper reports that thermal dip-pen nanolithography (tDPN) [10] can deposit polymer nanostructures from a heated AFM tip in a high vacuum environment (Figure 1b). In tDPN

• point inks such as polymers that also have low volatility and so may be deposited under a vacuum. Results and Discussion Our initial approach for depositing organic inks was to attempt DPN with octadecanethiol (ODT), a classic ink for DPN that reproducibly transfers to the substrate. However, it was
