| Summary: | Graphene and carbon nanotubes are nano materials which potential to replace <br />
<br />
<br />
<br />
<br />
<br />
a Semiconductor Metal Oxide sensor-based. Graphene consists of carbon <br />
<br />
<br />
<br />
<br />
<br />
atoms that arragement as honeycomb lattice and connected through sp2 bond, <br />
<br />
<br />
<br />
<br />
<br />
while carbon nanotubes are cylindrical material of nano materials formed by <br />
<br />
<br />
<br />
<br />
<br />
graphene. In this study, changes in the electronic state of graphene as a ethyl <br />
<br />
<br />
<br />
<br />
<br />
-methylbutyrate sensor and carbon nanotubes as a pollutant sensor (CO and <br />
<br />
<br />
<br />
<br />
<br />
SO2) were investigated. This study was conducted using Density Functional <br />
<br />
<br />
<br />
<br />
<br />
Theory (DFT) methode. The calculations showed a change of conductivity <br />
<br />
<br />
<br />
<br />
<br />
when graphene and carbon nanotubes interact with the gas. |
