Abstract :
The I-V characteristics of GaAs n+-i-p+-i-n + diode structures grown by MLE with source-drain distances from 500 Å to 950 Å have been measured at temperatures ranging from 77 K to 423 K. The analysis of experimental results indicates that the current flows over the static-induction-controlled potential barrier. On this basis, quantitative comparison with thermionic emission theory which assumes injection of ballistic electrons are made
