Query: Principles and simulations of high-resolution STM imaging with flexible
  tip apex   We present a robust but still efficient simulation approach for
high-resolution scanning tunneling microscopy with a flexible tip apex showing
sharp submolecular features. The approach takes into account the electronic
structure of sample and tip and relaxation of the tip apex. We validate our
model by achieving good agreement with various experimental images which allows
us to explain the origin of several observed features. Namely, we have found
that high-resolution STM mechanism consists of the standard STM imaging,
convolving electronic states of the sample and the tip apex orbital structure,
with the contrast heavily distorted by the relaxation of the flexible apex
caused by interaction with the substrate.
