Materials, Vol. 8, Pages 2769-2781: Investigation of the High Mobility IGZO Thin Films by Using Co-Sputtering Method

21.05.2015 | Hsu, Chao-Ming ; Tzou, Wen-Cheng ; Yang, Cheng-Fu ; Liou, Yu-Jhen, Materials, 2015

High transmittance ratio in visible range, low resistivity, and high mobility of IGZO thin films were prepared at room temperature for 30 min by co-sputtering of Zn2Ga2O5 (Ga2O3 + 2 ZnO, GZO) ceramic and In2O3 ceramic at the same time. The deposition power of pure In2O3 ceramic target was fixed ...

IJMS, Vol. 16, Pages 11629-11647: Optimization of NaOH Molarity, LUSI Mud/Alkaline Activator, and Na2SiO3/NaOH Ratio to Produce Lightweight Aggregate-Based Geopolymer

21.05.2015 | Razak, Rafiza Abdul; Abdullah, Mohd Mustafa Al Bakri; Hussin, Kamarudin ; Ismail, Khairul Nizar; Hardjito, Djwantoro ..., International Journal of Molecular Sciences, 2015

This paper presents the mechanical function and characterization of an artificial lightweight geopolymer aggregate (ALGA) using LUSI (Sidoarjo mud) and alkaline activator as source materials. LUSI stands for LU-Lumpur and SI-Sidoarjo, meaning mud from Sidoarjo which erupted near the Banjarpanji-1 ...

Sensors, Vol. 15, Pages 11805-11822: Modeling of Acoustic Emission Signal Propagation in Waveguides

21.05.2015 | Zelenyak, Andreea-Manuela ; Hamstad, Marvin A.; Sause, Markus G. R., Sensors, 2015

Acoustic emission (AE) testing is a widely used nondestructive testing (NDT) method to investigate material failure. When environmental conditions are harmful for the operation of the sensors, waveguides are typically mounted in between the inspected structure and the sensor. Such waveguides can ...

Sensors, Vol. 15, Pages 11442-11453: Design of an Embedded CMOS Temperature Sensor for Passive RFID Tag Chips

18.05.2015 | Deng, Fangming ; He, Yigang ; Li, Bing ; Zhang, Lihua ; Wu, Xiang ; Fu, Zhihui ; Zuo, Lei, Sensors, 2015

This paper presents an ultra-low embedded power temperature sensor for passive RFID tags. The temperature sensor converts the temperature variation to a PTAT current, which is then transformed into a temperature-controlled frequency. A phase locked loop (PLL)-based sensor interface is employed to ...
