“…Nano-size silicon-based structures have attracted a lot of interest in the current miniaturization trend toward nanophotonics and nanoelectronics (e.g., [1][2][3][4][5]). Particularly, the understanding of material properties changing with size, composition, and charge plays an important role.…”

Nano-size clusters are of great interest for understanding of fundamental properties and processes relevant for applied materials science such as heterogeneous catalysis. In this study, we present a newly developed dualtarget dual-laser ablation source, suitable for the production of binary clusters and their spectroscopic characterization. With the current design, an almost arbitrary mixing ratio can be achieved by altering different parameters such as the laser fluences. Boron and silicon targets are chosen for cluster production, illustrating the possibility to control the outcome ranging from pure boron over mixed SinBm to pure silicon clusters. As a test system, Si6B clusters are characterized by means of infrared-ultraviolet two-color ionization (IR-UV2CI) spectroscopy, combined with quantum chemical simulations. The most stable structure of Si6B (Cs, 2 A') predicted in our previous work is confirmed by the present experiment. Doping of Si7 with a single B atom has a drastic impact on the geometric, vibrational, and electronic properties.

-In this study, we fabricated an electrolyte-insulator-metal (EIM) device incorporating a high-k Al 2 O 3 sensing membrane using a porous anodic aluminum oxide (AAO) through a two-step anodizing process for pH detection. The structural properties were observed by field-emission scanning electron microscopy (FE-SEM) and X-ray diffraction patterns (XRD). Electrochemical measurements taken consisted of capacitance-voltage (C-V), hysteresis voltage and drift rates. The average pore diameter and depth of the AAO membrane with a pore-widening time of 20 min were 123nm and 273.5nm, respectively. At a pore-widening time of 20 min, the EIM device using anodic aluminum oxide exhibited a high sensitivity (56mV/pH), hysteresis voltage (6.2mV) and drift rate (0.25mV/pH).
