Hi can any one explain about quantum dot. My professor sugested me that it is the future evolution of electronics
 

Re: quantum dot

not only that spintran,set also future hopes.
 

Re: quantum dot

i think its a new technology where carriers will not flow as a bulk. But a transfer of single carriers.
 

Re: quantum dot

Quantum dot is also called an artificial atom. it's a zero dimension structure in which energy levels can be modified at will. this enables one to get radiation of any desired wavelength.
 

Re: quantum dot

Hi ,in quantum dots we have homogeneous and inhomogeneous broadening.
I need their exact equations and range of their values.
Would you please help me?
thank you very much.
 

Re: quantum dot

QD are also called nanocrystalline, can be treated as a single structure, that is you don't have to scale down to atomic level to study it.
also, nonlinear said, ther energy level can be easily modified.
they found great interest in many research area like next gen solar cells and quantum computing.
 

Hi,I have problem in transition matrix element equation in quantum dot soa.
Is it same for each state for example ground state and excited state and ....???
in some papers this equation has been written the same , but in others not?!
I'm really confused
please help me
thank you
