Summary form only given. Two-dimensional (2D) atomic crystals are considered to be very promising for nanoelectronics and spintronics applications. It provides a large class of materials proposed to be important for long distance spin transport, spin polarized tunneling and large spin-orbit coupling. Here I will discuss spintronic aspects of these 2D materials and their heterostructures. Graphene is considered to be an ideal material for spin transport due to the high mobility and long spin lifetime of the carriers. Recently, we demonstrated spin transport over distances of 16 μm and spin lifetimes up to 1.2 ns in large area CVD graphene on SiO2/Si substrate at room temperature [1]. Subsequently, using insulating h-BN as a tunnel barrier on graphene, we observe an enhancement in spin polarized tunneling [2], and its negative sign for thicker h-BN layers [3]. These signatures provide an experimental evidence of the spin filtering across the ferromagnet/hBN-graphene van der Waals heterostructures. We also employed 2D materials such as h-BN and MoS2 in ferromagnetic tunnel junctions for observation of tunnel magnetoresistance up to room temperature [4]. We further aim to address the issue of spin manipulation in graphene by employing heterostructures with other 2D semiconductors [5], topological insulators [6] and materials with novel spin textures. I will present both electronic and spintronic properties of these 2D materials and their heterostructures. These findings open a platform for exploring novel spin functionalities in 2D crystals and understanding the basic phenomenon that control their behavior.

Water lubrication has been attracting attention for environment-friendly society due to low CO2 emission. Furthermore, carbon-based materials such as diamond-like carbon (DLC) show the low friction properties in water lubrication due to the oxidation reaction on the surface in pre-sliding. However, the influence of oxidation reactions on low friction mechanism is still unclear. In this study, we clarify the structure change of DLC with the oxidation reaction in the pre-sliding using first-principles calculation, which suggests the low friction mechanism of DLC in water lubrication. The results show the structure change from sp3 carbon (Csp3) to sp2 carbon (Csp2) by the oxidation reaction on the surface. Furthermore, the Csp2 rich surface in water lubrication indicates the smooth sliding. We suggest that the structure change from Csp3 to Csp2 would affect low friction properties of DLC in water lubrication.

Age-related macular degeneration (AMD) is one of the major ophthalmic diseases that cause visual impairment and blindness. Although transplantation of autologous peripheral cells has been attempted by injecting cell suspensions, limited visual improvement resulted due to the low viability of the injected cells in the subretinal tissue. We developed micropatterned polymeric nanosheets toward local delivery of retinal pigment epithelial (RPE) cells. The micropatterned nanosheet directed growth and morphogenesis of the RPE cells, and allowed for the injection of an engineered RPE monolayer through syringe needles flexibly into the subretinal space of rat eyes. Such an ultra-thin flexible carrier has the promise of a minimally invasive delivery of organized cellular structures into narrow tissue spaces.

The proposed approach in this contribution concerns plasma deposition processes for engineering of multifunctional materials. It opens the way for transition from material level of development to system level of applications. This concept is applied for deposition of nanocomposite thin layers comprising a single layer of silver nanoparticles (AgNPs) embedded in silica-like host matrices at a controlled distance from the free surface with application in two distinguished fields, namely plasmonics to obtain large-area plasmonic embedded substrates and electrical engineering to control the charge injection in dielectrics. Structural, optical and electrical characterizations of the samples confirm the process efficiency.

We propose a hybrid cavity-channel structure to tune optical wavelengths using narrow-band resonances. High spectral selectivity and high angular dependency of the absorptance are reported due to the resonance between propagating surface plasmon modes and channel modes. By varying the incident angle, we could adjust both the position and the amplitude of the reflectance dips thus achieving highly efficient angular optical switches.

In this study, we have proposed an ingestible sensor platform utilizing gastric acid battery for daily healthcare. This platform has a fundamental application to precisely measure core body temperature as one of the most useful vital signs for health check. It also has the expandability to add various biosensors such as pH, pressure sensors etc.. The architecture without a conventional battery is essential to human body safety and environmental load reduction. In addition, the size and cost are expected to be reduced. This paper reports on the feasibility study of the proposed system and key technical elements.

We demonstrate dynamic modulation of a hybrid plasmonic-photonic crystal nanocavity through using monochromatic coherent acoustic phonons formed by ultrahigh-frequency surface acoustic waves to achieve strong optomechanical coupling. As a result, optical resonance wavelength shift and a large modulation bandwidth are shown at telecommunication wavelength for the hybrid nanocavity.

GaAs nanowires fabricated by an anodic etching have some advantages over conventional dry crystal growth and wet chemical dissolution techniques in terms of their formation. However, undesired electrical insulating behavior caused by deep interface states is observed. It is known that the interface states originate from the dissociated As atoms between GaAs core and Ga2O3 outer layer. Here, we investigated the effect of hydrogen exposure on anodically etched GaAs nanowires in liquid electrolyte in order to reduce the high density of interface states. As a result of different hydrogen exposure time, Raman spectra indicated that the longitudinal optical phonon intensities gradually decreased and slightly upshifted with increasing the electrolysis time. This means that the density of interface states was reduced by the hydrogen exposure. Based on the Raman analysis, we fabricated thin-film transistors (TFTs) using GaAs nanowires with 600 s of reverse electrolysis treatment. The TFT having nanowire random network channel showed good electrical properties (field-effect mobility: 2.3 cm2/Vs). This is comparable to TFTs using random network channel composed of other one dimensional materials.
