Query: Estimation of the lowest limit of 1/f noise in semiconductor materials   A lowest limit of 1/f noise in semiconductor materials has not yet been
reported; we do not even know if such a lowest limit exists. 1/f noise in
semiconductors has recently been brought into relation with 1/f noise in
quantum dots and other materials. These materials exhibit on-off states which
are power-law distributed over a wide range of timescales. We transfer such
findings to semiconductors, assuming that the g-r process is also controlled by
such on-off states. As a result, we obtain 1/f noise which can be expressed in
the form of the Hooge relation. Based on the intermittent g-r process, we
estimate the lowest limit of 1/f noise in semiconductor materials. We show that
this limit is inversely proportional to the dopant concentration; to detect the
lowest limit of 1/f noise, the number of centers should be as small as
possible. We also find a smooth dependence of 1/f noise and g-r noise on time.
