|The Original Point-Contact Transistor
The original point-contact transistor often behaved in true negative resistor fashion, but was never understood. The point-contact transistor was simply bypassed by advancing to other transistor types more easily manufactured and with less manufacturing variances.

McGraw-Hill, New York, 1965, p. 281-291.
Quoting p. 281 on point-contact transistors: "…the
theory underlying their function is imperfectly understood even after
almost a century… although the very nature of these units limits them
to small power capabilities, the concept of small-signal behavior, in
the sense of the term when applied to junction devices, is meaningless,
since there is no region of operation wherein equilibrium or theoretical
performance is observed. Point-contact devices may therefore be described as sharply
nonlinear under all operating conditions." Our comment is that point-contact transistors can easily be
developed into true negative resistors enabling COP > 1.0 circuits.
