momentum resolved transmission spectrum
« on: July 3, 2020, 16:34 »
What information can be obtained by momentum resolved transmission spectrum of a material?
For instance, if it shows that at a certain energy, certain k points show high transmission, what does that physically mean?

Hello,

>>> For instance, if it shows that at a certain energy, certain k points show high transmission, what does that physically mean?

For a periodic material, it means that for that specific value of energy and parallel momentum, the probability of ballistic electron/hole transport through the material will be high. For a device configuration, it means that the probability of source-to-drain ballistic electron transport will be high.

Best regards,
Daniele
