Mr. Sardela et al., NEGATIVE DIFFERENTIAL RESISTANCE AT ROOM-TEMPERATURE IN DELTA-DOPED DIODES GROWN BY SI-MOLECULAR BEAM EPITAXY, Applied physics letters, 64(13), 1994, pp. 1711-1713
Negative differential resistance effects at room temperature in delta-
doped diodes growth by silicon-molecular beam epitaxy are reported. Hi
gh tunneling current densities (almost-equal-to 4 kA/cm2) and peak-to-
value ratios close to 1.1 were achieved.
