| description | As per the electrical properties, chromium oxide (Cr2O3) nanoparticles are categorized as semiconductors and could be used as an alternative to conventional polymer and small molecule-based semiconductor materials used in organic thin film transistors (OTFTs). In the current investigation, the performance of two bottom gate bottom contact (BGBC) OTFTs comprising pentacene and chromium oxide (Cr2O3) nanoparticles as semiconductor material, respectively, was analyzed comparatively. SILVACO TCAD simulation tool was employed to analyze OTFT structures. Performance factors such as mobility in linear regime, saturation mobility, output current, ION/IOFF ratio, trans conductance, sub-threshold slope, and threshold voltage were explored to determine the superiority of Cr2O3 nanoparticles over pentacene. The linear mobility of Cr2O3 NPs was found to be 14.46 while the pentacene linear mobility was found to be 5.79. Furthermore, the solution mobility of the Cr2O3 NPs was found to be 1.239 and the pentacene solution mobility was 0.41. The Cr2O3 nanoparticles-based device exhibited a significantly higher Ids value of 17.5136 x 10-6 µA as compare to pentacene. Additionally, the Cr2O3 nanoparticles-based device showed an increased transconductance value of 12.241277 x 10-6 µS. The obtained results offer valuable insights into performance enhancement of OTFTs using Cr2O3 nano particles as semiconductor material, without altering the dimensions or operational voltages of the OTFT structures. These findings provide valuable insights for optimizing organic thin film transistors, thereby contributing to the advancement of efficient organic electronic systems. |
