By combining genetic algorithm optimizations, first-principles calculations and the double-exchange model studies, we have revealed that the exotic insulating ferromagnetism in ${\text{LaMnO}}_{3}$ thin film originates from the previously unreported G-type ${d}_{3{z}^{2}\ensuremath{-}{r}^{2}}/\phantom{\rule{0.0pt}{0ex…
The formation of isotactic poly(propylene) (iPP) and polycarbonate (PC) nanowires of tunable diameter was demonstrated by melt-wetting the polymer into nanoporous anodic alumina. The crystallization process was analyzed using differential scanning calorimetry. A transition from hetero- to homogeneous crystallization w…
Condensed matter systems that are both low-dimensional and strongly interacting often exhibit unusual electronic properties, with the high-Tc superconductivity in cuprates and iron pnictides as the most prominent example. A metallic state with the strongest electron correlation is realized in heavy fermion compounds,…
In solids containing elements with f−orbitals, the interaction between f -electron spins and those of itinerant electrons leads to the development of low-energy excitations with heavy effective mass. Previously, we used the scanning tunneling microscope (STM) to visualize the scattering of quasiparticles and detect th…
Graphene is known for its high carrier mobility and high saturation velocity [1–3]. The majority of graphene transistors in the literature—including MOSFETs, barristors, and tunneling FETs—have a gate separated from the channel by a conventional or high-K dielectric layer [4–6]. In this paper we demonstrate for the fi…
Two dimensional membranes have become the playground for both theorists and experimentalists due to their unique intrinsic properties emerged from simple lattice structures. They are the new focus of spintronic applications. Therefore, it is important that we have a clear view of the relaxation processes in spin trans…
Nanoscale electronic devices like field-effect transistors have long promised to provide sensitive, label-free detection of biomolecules. Single-walled carbon nanotubes press this concept further by not just detecting molecules but also monitoring their dynamics in real time. Recent measurements have demonstrated this…
Ferroelectric and Multiferroic tunnel junctions (magnetic tunnel junction with a ferroelectric barrier) have become one of the very promising approaches to new generation of multifunctional devices. A large tunneling electroresistance (TER) (the resistance on-off ratio) is very desirable for utilizing the device as a…
Guiding the self-assembly of materials by controlling the shape of the individual particle constituents is a powerful approach to material design. We show that colloidal silica superballs crystallize into canted phases in the presence of depletants. Some of these phases are consistent with the so-called "Λ1" lattice t…
Topological materials (TMs) host protected surface states that emerge from strong spin orbit coupling in the bulk and on the surface. While their remarkable properties have generated much interest, previous studies have shown nanoscale variations in their surface state properties [1,2], prompting the development of a…
This paper describes an electrochemical technique for growing adhesive copper oxide films on copper with attractive colors ranging from gold-brown to pearl with intermediate colors from red violet to gold green. The technique consists of anodically dissolving copper at transpassive potentials in hot sodium hydroxide,…
The rule of the interface in systems including polymer composites and block-‐ copolymer interacting with biomembrane has been investigated by computational approach. In particular, for the polymer composite investigation, a system composed of PMMA embedding a silica nanoparticle of 3 nm (diameter), and an analogue sy…
We have measured the lattice constants and the structure factors of three salt-like crystal structures (NaCl, K-Cl, Rb-Cl) using a X-rays produced with a Cu X-ray tube operated at 30 kV and Geiger-Mueller counter that is incorporated in the physics department's new x-ray diffraction machine. The machine (Tel-X-Ometer)…
Abstract : This project was focused on the development of switches using phase change materials from chalcogenide compounds. New phase change device structures were developed and a new thermoelectric model capable of describing the device nonlinear behaviors was introduced and validated.
Asymmetric contacts or split gate geometries can be used to obtain rectification, electroluminescence (EL) and photocurrent from carbon nanotube field effect transistors. Here, we report devices with both split gates and asymmetric contacts and show that device parameters can be optimised with an appropriate split gat…

An Anacystis nidulans photolyase enzyme containing two chromophore cofactors was simulated for a photoreaction DNA repairing process via molecular dynamics (MD) method. A novel approach has been introduced for the electron transfer between the FAD (flavin adenine dinucleotide; flavin) molecule and CPD (cyclobutane pyr…
We present our results of (20-21) GaN growth on (22-43) patterned sapphire substrates. The substrates are patterned by etching trenches with c-plane-like side-facets. On these facets, the metalorganic vapor phase epitaxy (MOVPE) GaN growth starts in c-direction and forms triangularly shaped stripes eventually coalesci…
Nanotransistors offer great prospect for the development of innovative THz detectors based on the non-linearity of transport characteristics. Semiconductor nanowires are appealing for their one-dimensional nature and intrinsically low capacitance of the devices, while graphene, with its record-high room-temperature mo…
