“…For example, control of deposition of atoms and bridging molecules in three-dimensionally architected structures can create novel device concepts such as atomic switches [67][68][69] and single molecule logic gate. 70,71 Architecting atoms by rational means into materials has resulted in novel and highly enhanced functions as can be seen in photocatalysts 72,73 and spintronics materials. 74,75 Forming stimuli-responsive materials with softly deformable structures can lead to the development of innovative and unusual functional materials such as self-powered sensors 76 and hand-operatable molecular screening systems.…”

Although progress in nanotechnology is anticipated to stimulate the development of innovative materials, the areas of nanotechnology and materials science are somehow separated with little common ground in current technologies. Nanotechnology has some analytical aspects that are beneficial mainly to the nanoscopic sciences at the atom or molecular levels. Experience of these advanced techniques has only been applied in synthetic approaches to macroscopic materials in rather immature level. Forming nanomaterials into hierarchic and organized structures is a rational way of preparing advanced functional materials. Recently, one of us coined the term materials' nanoarchitectonics to express this innovation. This review focuses on recent research to develop functional materials by forming nanomaterials into organized structures, especially in well-ordered layered structural motifs. This layered nanoarchitectonics can be achieved by using the versatile technology of layer-by-layer assembly. Reassembly of bulk materials into novel layered structures through layered nanoarchitectonics has created many innovative functional materials in a wide variety of fields as can be seen in ferromagnetic nanosheets, sensors, flame-retardant coatings, transparent conductors, electrodes and transistors, walking devices, drug release surfaces, targeting drug carriers and cell culturing.

“…The new molecular electronic approach called QHC (standing for Quantum Hamiltonian Computing) 1 has been recently proposed and demonstrated experimentally in which the complex functionality of a Boolean logic gate is fully implemented inside a single molecule without integrating or mimicking standard electronic components like rectifiers, switches, transistors or even qubit-like chemical groups along the molecular structure 2 . QHC is based on the phenomenon that the eigenstates of a well-designed quantum system can be shifted in energy relative to a reference energy to conform to a Boolean truth table by locally perturbing this quantum system, where the local perturbations serve as logical inputs 2 . The advantage of this approach is that the logical output can be measured locally at any position on the quantum system where the shifted in energy quantum eigenstates have a large electronic probability density.…”

We present a combined experimental and theoretical study of the electronic properties of close-spaced dangling-bond (DB) pairs in a hydrogen-passivated Si(001):H p-doped surface. Two types of DB pairs are considered, called “cross” and “line” structures. Our scanning tunneling spectroscopy (STS) data show that, although the spectra taken over different DBs in each pair exhibit a remarkable resemblance, they appear shifted by a constant energy that depends on the DB-pair type. This spontaneous asymmetry persists after repeated STS measurements. By comparison with density functional theory (DFT) calculations, we demonstrate that the magnitude of this shift and the relative position of the STS peaks can be explained by distinct charge states for each DB in the pair. We also explain how the charge state is modified by the presence of the scanning tunneling microscopy (STM) tip and the applied bias. Our results indicate that, using the STM tip, it is possible to control the charge state of individual DBs in complex structures, even if they are in close proximity. This observation might have important consequences for the design of electronic circuits and logic gates based on DBs in passivated silicon surfaces.
