Thin organic films can be realized by depositing single molecules on surfaces, which is the first step for the so-called bottom
elsewhere [19], coupled to a chamber devoted to organic molecular beam epitaxy (OMBE). The OMBE chamber was designed and built in collaboration with 5Pascal srl. (via Boccaccio 108, 20090 Trezzano sul Naviglio, Milano, Italy). The OMBE system is equipped with four Knudsen cells, whose crucibles are
controlled within 0.5 °C. One of the cells is filled with Zn-TPP molecules provided by Sigma-Aldrich and purified in vacuum by several cycles of annealing at 150 °C and flashes at 310 °C, until the pressure in the OMBE chamber was stable in the low 10−7 Pa range. The molecule sublimation was achieved at a

≡C–CN (2) were deposited from a quartz crucible held at T = 479 K by organic molecular beam epitaxy (OMBE) onto a clean Ag(111) crystal held at ≈300 K.
Subsequently, Gd atoms were sublimated by means of electron beam evaporation from an outgassed Gd rod (99.9%, MaTecK GmbH, 52428 Jülich, Germany
