We have performed an optoelectronic measurement of the impulse response of an ultrafast sampling oscilloscope with a nominal bandwidth of 100 GHz within a time window of approximately 100 ps. Our experimental technique also considers frequency components above the cut-off frequency of higher-order modes of the 1.0 mm coaxial line, which is shown to be important for the specification of the impu...
Recently, many new optoelectronic sources of freely propagating THz radiation have been demonstrated. l-l4 Common to all these sources has been the problem to properly characterize the emitted THz radiation with receivers of limited bandwidths. The broadest bandwidth receivers have used ion-implanted, silicon-on-sapphire (SOS), photoconductive switches. In general, the limiting response of phot...
In this work, we present results on the growth of centimeter-scale pentacene crystals using physical vapor transport method in a dual-temperature zone horizontal furnace. It was established that intensive crystal processes occurred transition regions with sudden temperature changes, while practically not observed slightly varying temperatures. During growth, co-precipitating golden needle-like ...
