We report efficient photoconductivity multiplication in few-layer 2H-MoTe<sub>2</sub> as a direct consequence of an efficient steplike carrier multiplication with near unity quantum yield and high carrier mobility (∼45 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup>) in MoTe<sub>2</sub>. This photoconductivity multiplication is quantified using ultrafast, excitation-wavelength-dependent photoconductivity measurements employing contact-free terahertz spectroscopy. We discuss the possible origins of ...[more]
