It strictly means the temperature coeffecient of a particular property of silicon: as the temperature rises, the value of this property falls. Such as electrical resistance.
negative degrees show how cold it is
Yes, the mean can be negative if the numbers being averaged are negative. For example, if you are averaging temperatures and all of the temperatures are below zero, your average temperature will be a negative number.
If you mean a photovoltaic cell, then no. A photovoltaic cell requires a metalloid to function. The metalloid such as silicon can take on two different types: negative silicon or positive silicon which provides for a slight electric potential. Photons emitted from the sun excite electrons on the surface of the silicon and induce a current between the two plates.
There is no such compound as silicon sulfate. Do you mean silicon sulfide, SiS2 ?
A positive temperature coefficient means that the resistance of a material increases as temperature increases. Conversely, a negative temperature coefficient means that the resistance decreases as temperature rises. These coefficients are important in understanding how materials respond to changes in temperature and are commonly seen in the properties of semiconductors and resistors.
silicon dibromide
You mean Celsius, the temperature scale? Yes,certainly; it can be as low as negative 273 degrees C, which is absolute zero on the Kelvin scale.
C is a conductor, so valence and conduction bands overlap. if you mean SiC, silicon carbide, energy gap is ~2.86eV @ 300K (ambient temperature)
Silicon is a element.! this is because anything from the periodic table is in fact elements! :)
The temperature coefficient of a thermistor is a measure of how much its resistance changes with temperature. It is typically expressed in units of percent resistance change per degree Celsius. Negative temperature coefficients mean the resistance decreases as temperature increases, while positive coefficients mean the resistance increases with temperature.
Si stands for silicon.
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
