Remarks :
-----------------Abstract-----------------
When analyzing the behavior of solid state devices, it is customary to assume
that the acceptors and donors in the semiconductor are immobile at room
temperature. This assumption becomes questionable as the size of the device
drastically decreases. The question arises what happens to the current
voltage, I-V, relations if those ionic defects are allowed to move. In
this talk we consider a device of the form metal1|semiconductor|metal2
where the acceptors in the semiconductor are mobile. We limit the discussion
to the case in which the electrodes do not allow exchange of material with
the surroundings, only electrons. The motion of the acceptors ceases under
steady state but they redistribute under changes in the applied voltage.
This affects the space charge distribution and thus also I-V relations.
The solutions for the I-V relations as well as the hole and acceptor
distribution are presented. We find that in the very thin sample limit the
device properties are independent of the acceptor motion. Otherwise the
device properties show dependence on the acceptor motion. The I-V relations
are compared to the measured ones for the device Cu|Cu2O|metal (which was
used as a rectifier in the pre Si era). Cu2O is known to be a p-type

Abstract
This talk will focus on supramolecular polymer chemistry, in particular,
molecular recognition in the interior (core) of dendrimers and along polymer
chains. The first part of the talk will focus on recognition driven
assembly, specifically our efforts to create new polymeric architectures
using DNA base-pairing interactions. One major hurdle to be overcome is the
development of subunits that hydrogen bond one another with very high
stability and fidelity. Recent developments in this area as well as
applications to self-assembling dendrimers will be discussed.
Semi-quantitative approaches to predicting complex and dimer stabilities
will also be highlighted. In the second part of the talk our recent
attempts to create binding sites within dendrimers via molecular imprinting
will be highlighted.
