Effect of Ligands on the Photoconductivity of HgTe Nanoplatelets
View through CrossRef
Near-IR semiconductor colloidal nanoplatelets (NPs) are a new and promising class of materials for the development of photodetectors because they can effectively absorb visible and infrared optical radiation. In this work, we study the photoconductivity of HgTe colloidal nanoplatelets with ligands of 1,2-ethanedithiol and tetrabutylammonium iodide. It has been shown that the choice of ligands is a key factor in achieving high operational characteristics. It has been shown that the photoconductivity sensitivity reaches 0.995 and the specific detectivity reaches 1.2·109 J Jones when 1,2-ethadithiol is used as ligands. Keywords: Near-IR, photodetectors, specific detectivity, EDT, TBAI.
