Typically semiconducting materials are used as the non-equilibrium charge carriers created by optical excitation can efficiently be separated to create electric current. However, this process doesn\u2019t occur in metallic materials besides a few exceptions as the number of intrinsic charge carriers are far greater than the photoexcited ones thus no significant photocurrent generation takes place.<\/p>\n<p>Dr. Kas\u0131rga\u2019s group demonstrates that in an exemplary metallic layered transition metal dichalcogenide, NbS&lt;sub&gt;2&lt;\/sub&gt;, because of thermoelectric effects photocurrent generation is possible. \u201cThis study could enable fabrication of highly efficient all transition metal dichalcogenide photodetectors and solar cells as NbS &lt;sub&gt;2&lt;\/sub&gt; can be used as an efficient contact to most semiconducting 2D materials\u201d said MSN PhD candidate Naveed Mehmood.<\/p>\n<p>The study has been published in Physical Review B.
