Preparation and characterisation of transition metal oxide micro-thermistors and their application to immersed thermistor bolometer infrared detectors

Structural and electrical properties of Mn1.56Co0.96Ni0.48O4 NTC thermistor films

“…On the basis of the above results, the MCN films have higher ˛, SF and appropriate resistance. Hence, it is attractive for development of temperature sensors and infrared detector devices [31].…”

Positron annihilation characterization of free volume in micro- and macro-modified Cu0.4Co0.4Ni0.4Mn1.8O4 ceramics

“…Adequate understanding of correlation between porous and void structures of such materials is still in focus of scientific and commercial interests [4,5]. The spatial ordering arrangement in atomic positions is taken as main determinant for their functional properties.…”

Formation and growth of manganese phosphate passivation layers for NTC ceramics

“…Semi-conductive ceramics with large negative temperature coefficient (NTC) based on solid solutions of transition-metal oxides, in most cases, due to their long-term stability, Mn 3 O 4 , Co 3 O 4 and NiO with the spinel structure are widely used in various industrial and domestic applications [1][2][3]. Usually, passivation layers, such as phosphate, polymer and glass, are coated onto the surfaces of NTC chip thermistors to prevent the degradation induced by the electroplating process.…”
