| Abstract Scope |
With the rapid rise in wireless technology, Radio frequency (RF) energy harvesting is receiving an increased attention in today’s digital era due to its potential to replace or improve the longevity of low-powered IoT devices, sensors and micro electronic devices. Here, we have focused on developing an RF energy harvesting device using few-layered earth abundant two-dimensional (2D) Pyrite (FeS2).2D Pyrite was synthesized from bulk Pyrite using liquid phase exfoliation method. A Schottky diode setup was fabricated by employing Ti/2DFeS2/ITO configuration. RF energy harvesting was demonstrated in FM band (88-110MHz) and VHF band (140-170) MHz.The device extracted RF energy and gave an output DC voltage of a maximum of 3.5V with an efficiency of 30 %. Density functional theory (DFT) studies were performed revealing the impact of the Giant Stark Effect (GSE) in enhanced RF sensitivity of 2D FeS2. |
