850-nm vertical-cavity laser diodes with copper-plated heat sinks were fabricated and tested. Vertical-cavity surface-emitting lasers with 10μm aperture diameter and 4μm of electroplated copper demonstrated a maximum −3dB modulation bandwidth of more than 16GHz and a resonance frequency of more than 11GHz at bias current of only 5.4mA,(More)

Aluminium nitride (AlN) is a promising material for high temperature applications in harsh environments. Reactively sputter-deposited AlN from an aluminium target is an interesting piezoelectric thin film material with high CMOS compatibility. The properties of thin films differ from bulk material, especially at high temperatures. Therefore, the influence(More)
The purpose of this study was to compare isometric strength of elbow extensors measured in supine- and prone-lying positions at elbow flexion angles of 45 and 90 degrees. Twenty-two male subjects under single-blind procedures participated in the study. Each subject participated in both supine-lying and prone-lying measuring protocols. Calibrated cable(More)
