The current values are varied from 10 nA to 0.1 A. The sensitivity of the diode is observed to increase for lower current values in the high temperature range. The rapid increase of the forward voltage at low temperatures is observed to be suppressed considerably by reducing the current. This study helps us to conclude that for all practical purposes such commercial diodes ͑prescribed for a particular current value of 10 A͒ can be operated for a wider range of current values, with suitable calibration data.

A highly stable temperature sensor based on Au/Cu/n-Si Schottky barrier diodes dependent on the inner metal thickness

“…Schottky barrier diodes (SBDs) are generally used for designing sensors for temperature, pressure and atmospheric gas composition [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. A SBD is also called a * Author to whom any correspondence should be addressed.…”

Barrier height inhomogeneities induced anomaly in thermal sensitivity of Ni/4H-SiC Schottky diode temperature sensor

“…Among the commercially available technologies for sensing harsh environment temperature, silicon carbide (SiC) based devices were found to be an excellent candidate. 12 Therefore, this paper addresses the thermal sensitivity behavior of a temperature sensor based on state-of-art material, i.e., SiC, with small size. The most common temperature sensors among all commercially available sensors, which are being used in harsh environments, are optical sensors, thermocouples, resistive temperature detectors, thermistors, and semiconductor temperature sensors.…”

Study on the temperature sensing capability of a light-emitting diode

“…Temperature dependence of the current-voltage characteristics of a semiconductor p-n junction have been utilized in temperature measurement since last few decades. [1][2][3][4][5][6] It has been observed that the forward voltage drop across a p-n junction at constant current varies almost linearly with temperature. The slope of temperature-voltage curve depends on the value of forward current and it decreases towards higher currents.…”
