Understanding Semiconductors: Intrinsic, Extrinsic, and Nonstoichiometric

AI Thread Summary
Intrinsic semiconductors are undoped materials that have a pure crystal structure, allowing for minimal electrical conductivity. Extrinsic semiconductors are created by doping intrinsic materials with impurities to enhance conductivity, introducing charge carriers. Nonstoichiometric semiconductors contain a deviation from the ideal ratio of elements, affecting their electrical properties and behavior. Understanding these distinctions is crucial for applications in electronics and materials science. The significance of stoichiometry plays a vital role in determining the performance of semiconductor materials.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
