One-dimensional (1D) metal-oxide nanostructures are ideal systems for exploring a large number of novel phenomena at the nanoscale and investigating size and dimensionality dependence of nanostructure properties for potential applications The construction and integration of photodetectors or optical switches based on such nanostructures with tailored geometries have rapidly advanced in recent years Active 1D nanostructure photodetector elements can be configured either as resistors whose conductions are altered by a charge-transfer process or as field-effect transistors (FET) whose properties can be controlled by applying appropriate potentials onto the gates Functionalizing the structure surfaces offers another avenue for expanding the sensor capabilities This article provides a comprehensive review on the state-of-the-art research activities in the photodetector field It mainly focuses on the metal oxide 1D nanostructures such as ZnO, SnO(2), Cu(2)O, Ga(2)O(3), Fe(2)O(3), In(2)O(3), CdO, CeO(2), and their photoresponses The review begins with a survey of quasi 1D metal-oxide semiconductor nanostructures and the photodetector principle, then shows the recent progresses on several kinds of important metal-oxide nanostructures and their photoresponses and briefly presents some additional prospective metal-oxide 1D nanomaterials Finally, the review is concluded with some perspectives and outlook on the future developments in this area

A comprehensive review of one-dimensional metal-oxide nanostructure photodetectors

A grand family of two-dimensional (2D) materials and their heterostructures have been discovered through the extensive experimental and theoretical efforts of chemists, material scientists, physicists, and technologists. These pioneering works contribute to realizing the fundamental platforms to explore and analyze new physical/chemical properties and technological phenomena at the micro-nano-pico scales. Engineering 2D van der Waals (vdW) materials and their heterostructures via chemical and physical methods with a suitable choice of stacking order, thickness, and interlayer interactions enable exotic carrier dynamics, showing potential in high-frequency electronics, broadband optoelectronics, low-power neuromorphic computing, and ubiquitous electronics. This comprehensive review addresses recent advances in terms of representative 2D materials, the general fabrication methods, and characterization techniques and the vital role of the physical parameters affecting the quality of 2D heterostructures. The main emphasis is on 2D heterostructures and 3D-bulk (3D) hybrid systems exhibiting intrinsic quantum mechanical responses in the optical, valley, and topological states. Finally, we discuss the universality of 2D heterostructures with representative applications and trends for future electronics and optoelectronics (FEO) under the challenges and opportunities from physical, nanotechnological, and material synthesis perspectives.

石墨烯（graphene）是一种由碳原子以sp2杂化轨道构成的六角型呈蜂巢晶格的单层片状结构的新材料。英国曼彻斯特大学物理学家安德烈·海姆和康斯坦丁·诺沃肖洛夫，因成功地在实验室中从石墨中分离出石墨烯，而共同获得2010年诺贝尔物理学奖。目前，它是世界上最薄却也是最坚硬的纳米材料。它几乎完全透明，导热系数高于碳纳米管和金刚石，而电阻率只有约10-6Ω·cm，比铜或银更低，为目前世上电阻率最小的材料。因其电阻率极低，电子迁移速度极快，因此被期待可用于发展出更薄、导电速度更快的新一代电子元件或晶体管。

石墨烯（graphene）

Graphene is a remarkable material with great potential in many applications due to its chemical and physical properties. In this review we briefly present the recent research progress (2016-2018) in graphene and graphene-based nanomaterials synthesis and discuss the practical aspects of using the materials produced via these methods for different graphene-based applications.

A brief overview on synthesis and applications of graphene and graphene-based nanomaterials

Graphene is a material with unique properties that can be exploited in electronics, catalysis, energy, and bio-related fields Although, for maximal utilization of this material, high-quality graphene is required at both the growth process and after transfer of the graphene film to the application-compatible substrate Chemical vapor deposition (CVD) is an important method for growing high-quality graphene on non-technological substrates (as, metal substrates, eg, copper foil) Thus, there are also considerable efforts toward the efficient and non-damaging transfer of quality of graphene on to technologically relevant materials and systems In this review article, a range of graphene current transfer techniques are reviewed from the standpoint of their impact on contamination control and structural integrity preservation of the as-produced graphene In addition, their scalability, cost- and time-effectiveness are discussed We summarize with a perspective on the transfer challenges, alternative options and future developments toward graphene technology

The growth of III–V nitrides heterostructure on Si substrate by plasma-assisted molecular beam epitaxy

A prototype ultraviolet (UV) photodetector based on photoelectrochemical (PEC) cell from material synthesis up to assembly was demonstrated in this work. Self-organized titanium dioxide (TiO2) nanotube layers (1 and 5 μm thicknesses) prepared by electrochemical anodization were applied as the sensing layer in the photodetector. A printed circuit board (PCB) platform with physical size of 2 cm × 2 cm was designed to mount the sensing layer. The photodetector system comprised of a sandwich structure can be described as glass/ITO/electrolyte/TiO2 nanotube layer/Ti/PCB platform. For this system, a low applied voltage of 0.5–1 V was required to drive the photodetector. TiO2 nanotube layers have shown positive photoresponse in the entire UV spectral region (λ = 250–400 nm, classified as UV-A, B and C). In particular, the highest response with >850 sensitivity, and responsivity of ≈740 mA/W had been achieved by the 5 μm TiO2 nanotube layer for detection in the UV-A region, and the respective rise and decay time were 0.88 and 1.28 s. This work shows that the sandwich structure PEC cell UV photodetector with TiO2 nanotube layer as sensing layer is stable, highly sensitive and provides rapid response. Such platform can be potentially applied for other sensing materials as an efficient photodetector.
