in the marked red line
how they comeup with the fact the the velocity increases by this amount
?
i didnt see this expression before in this book
Cant understand this line in the book(semiconductor nightmare 4)

SUMMARY
The discussion centers on the derivation of the velocity increase in the context of semiconductor physics, specifically referencing the equation F = ma and its application to electric fields. The expression for velocity change, ∆v = -eEt/m, is derived from the force equation where F equals the product of charge (q) and electric field (E). This relationship is crucial for understanding particle dynamics in semiconductor materials.

Hi nhrock3!
F = ma = m(dv/dt) …
In this case, F = qE = -eE, so m(dv/dt) = qE, so ∆v = -eEt/m.
