Figure 5From: Synthesis and high sensing properties of a single Pd-doped SnO2 nanoribbonSensitive comparison of a single SnO 2 nanoribbon with Pd-doped SnO 2 nanoribbon for ethanol, ethanediol, and acetone gases. (a) Rs versus T curves of a Pd-SnO2 NB to ethanol at 100 ppm; Rs versus T curves of a SnO2 NB to ethanol at 100 ppm in inset. (b) The bar diagram of two devices responding to different gases at 230°C.Back to article page
