SEMICONDUCTORS AND NANODEVICESG
Carrier transport, photonics and sensing in group IV-based and other semiconductors nano devices
The new composites and nanostructures of group IV materials provide a platform for advanced devices for Nanoelectronics, Photonics and Sensors. The symposium will focus on group IV materials, nanostructures and related devices with the objective to bring together scientists working in different application fields.
The scope of the proposed symposium will include experimental and theoretical innovations related to group IV nanoelectronics, nanophotonics and nanosensing. An emphasis will be made on high mobility materials suitable for fast devices, light emission and light absorption.
These topics have attracted an increasing attention in the recent years for various applications, including infrared communication and imaging. The very critical issues are therefore carrier transport properties and lifetimes which will be reflected in the symposium program.
The photonic devices of particular interest are detectors, light emitting sources, waveguides, optical modulators and CMOS devices. Additional topics in the symposium scope are defect characterization, engineering and the impact of crystal quality on the properties of electronic and photonic devices.
Moreover, integrated photonic devices are recently emerging in the field of biological and chemical sensing allowing ultra-high sensing performances and efficient CMOS-compatible systems.
Simulations and calculations of nanodevices, predicting their physical properties and performances are vital to successful device design and optimization. This is particularly important when novel Si-Ge-Sn-C alloys and structures are involved; and in case of nano scale devices, where conventional approximations can no longer be applied.
The symposium will bring together the whole chain starting with novel technological developments in the field of material synthesis; subsequently, material characterization, device design and fabrication; and finally, device characterization, simulation and modeling. New applications will be welcome as well.

Resume : Copper Indium Gallium Selenide (CIGS) solar cell has been actively researched as clean energy technology with advantage of being flexible and thin film. However, conventional CIGS solar cells faced limitations as their photoactive layer cannot sufficiently absorb light due to reflection of incident light. To overcome these drawbacks, we fabricated PDMS film with randomly formed patterns, so-called “Optical haze film” through a combination of simple Aluminum hydrolysis with imprinting method. Optical haze film increase absorption of solar cell by extending light path of incident light. Also, Random nanostructures formed on film reduce reflection of incident light by gradually changing refractive index of interface surface. By simply attaching the haze film onto CIGS solar cell, we improve photo-conversion efficiency of CIGS solar cell by 8.8% from 9.78 to 10.64%.

Resume : Gold nanoparticles (AuNPs) have been investigated widely because of their unique catalytic, optical, and electrical properties. In particular, among various shape, well-defined spherical AuNPs could provide simplicity and precision for optical engineering research (i.e., Fano-like resonance, extinction coefficient, and scattering). Recently, we have established a synthetic route for obtaining monodisperse, ultra-smooth, and highly spherical AuNPs larger than 30 nm by advancing the experimental conditions of chemically etching faceted Au octahedron; unprecedented quality of these ideally spherical AuNPs with a relatively large size have been confirmed by our spectral measurements. In extension research, we have systematically studied the UV-Vis absorbance behavior and extinction coefficients for our ideally spherical. Also, the super-spherical AuNPs allowed to deterministic and reliable assembly in a short time as metamolecules by AFM-enabled manipulation, in comparison with polygonal shaped AuNPs.
