Estimation of Phase Coherent Length of Hot Electrons in GaInAs Using Resonant Tunneling Diodes
View through CrossRef
The relationship between the resonant level width of resonant tunneling diodes
(RTD) and the coherent length of electrons is investigated theoretically. The resonant
level widths were measured using the second derivative of the J-V characteristics
of GaInAs/InP RTDs. Measured data are compared with theory, and it is estimated that
the coherent length of hot electrons is longer than 50 to 90 nm.
