“…The application of surface technologies focused on the manufacture of semiconductor films has had a great impact on studies of mechanics, as well as in electronic issues, which have directly influenced, the miniaturization of electronic components. [6][7][8][9][10][11][12][13][14][15][16][17] Multiple techniques allow the manufacture of OS films, deposition by vacuum thermal deposition is one of the most used in the manufacture of optoelectronic devices. [18][19][20][21][22][23] During thermal deposition, the OS is brought to a vapor phase by heating it at low pressures (10 À 6 -10 À 8 torr).…”

In this work, it is proposed the development of organic semiconductors (OS) based on uranyl(VI) complexes. The above by means of the synthesis and the characterization of the complexes by Infrared spectroscopy, Nuclear magnetic resonance spectroscopy, mass spectrometry, and X‐ray diffraction. Films of these complexes were deposited and subsequently, topographic and structural characterization was carried out by Scanning Electron Microscopy, X‐ray diffraction, and Atomic Force Microscopy. Additionally, the nanomechanical evaluation was performed to know the stiffness of uranyl films using their modulus of elasticity. Also, the optical characterization took place in the devices and their bandgap value ranges between 2.40 and 2.93 eV being the minor for the film of the uranyl complex with the N on pyridine in position 4 (2 c). Finally, the electrical behavior of the uranyl(VI) films was evaluated, and important differences were obtained: the uranyl complex with the N on pyridine in position 2 (2 a) film is not influenced by changes in lighting and its current density is in the order of 10−3 A/cm2. The film with uranyl complex with the N on pyridine in position 3 (2 b) and 2 c presents a greater current flow under lighting conditions and two orders of magnitude larger than in film 2 a. In these films 2 b and 2 c, ohmic behavior occurs at low voltages, while at high voltages the charge transport changes to space‐charge limited current behavior.

“…centrifugal forces), dust impact, corrosive substances and other environmental hazards. Therefore, it is used for various adhesion test methods, such as tensile adhesion test, cross hatch, scotch tape, peeling test, scratch test, pull-off test, etc [ [107] , [108] , [109] , [110] ]. The only study conducted on the durability of the catalytic coating on the surface of the substrate in the spinning disc photocatalytic reactor system was conducted by Mirzaei et al, in 2017.…”
