A facile in-situ growth of large area flexible α-MoO3 microsheets aligned arrays for temperature sensor

We reported a facile, environmentally friendly, in-situ growth and economic thermal oxidization method for growing large area, flexible and aligned alpha-MoO3 microsheets arrays (MMAs) on Mo foil. The surface morphology, and cross-sectional images show that the size of rectangle and height of alpha-MoO3 microsheets arrays increase with increasing oxidization temperature, and these arrays are strongly adhering to Mo substrate. The aligned alpha-MoO3 microsheets arrays have a preferential (100) orientation of the crystallites. Additionally, this kind of MMAs demonstrates the excellent flexibility. Based on it, a simple temperature sensor was developed through interdigital electrodes and presented the high-performance temperature sensing property, demonstrating it would be a good potential in variety of flexible inorganic semiconductor microdevices as well as tiny integrated devices.
