An investigation of electron mobility in Leucaena Leucocephala Wood Plastic Composite for THz photoconductive antenna radiation enhancement

Photoconductive antenna (PCA) is promising devices that are most frequently used in Terahertz (THz) generation and detection system. However, THz PCA has limitation due to low output power (μW) and inefficient sources. Substrate material is one of parameters considered to enhance the THz output power radiation of PCA. This paper is aimed to investigate the electron mobility in Leucaena Leucocephala (Local Malaysian name Petai Belalang) Wood Plastic Composite for THz PCA radiation enhancement using Hall-effect measurement system (ECOPIA HMS-3000) equipment by 300 Kelvin room temperature with variance input currents. Data gathered by this material is compared with material made of 100% polypropylene polymer relatively with the same data input and supported by the literature research results.
