We present the implementation of an efficient terahertz (THz) photoconductive antenna (PCA) emitter design that utilizes high mobility carriers in the two-dimensional electron gas (2DEG) of a modulation-doped heterostructure (MDH). The PCA design is

Epitaxial low temperature grown GaAs (LT-GaAs) on silicon (LT-GaAs/Si) has the potential for terahertz (THz) photoconductive antenna applications. However, crystalline, optical and electrical properties of heteroepitaxial grown LT-GaAs/Si can be very

Terahertz (THz) emission increase is observed for GaAs thin films that exhibit structural defects. The GaAs epilayers are grown by molecular beam epitaxy on exactly oriented Si (100) substrates at three different temperatures (Ts = 320ºC, 520ºC and

Carrier dynamics of two LT-GaAs layers grown using similar parameters, but on different substrates were studied. The behavior of the time-resolved terahertz transmission was observed to differ in trapping time constants, as well as in fluence-depende

We investigate the effects of an externally applied magnetic field on the terahertz (THz) emission of Gallium Manganese Arsenide (GaMnAs) films grown via molecular beam epitaxy (MBE). Results show that low Mn-doping in GaMnAs resulted to increased TH

GaAs films were grown on Si (100) substrates with a “two-step buffer” growth technique using molecular beam epitaxy, wherein a low temperature GaAs buffer is grown at two substrate temperatures prior to the GaAs layer. Results of GaAs layer growt
