The scanning tunneling microscope has been used to perform research across a wide variety of fields. The study of high temperature superconductivity has resulted in an almost incomprehensible number of publications over the past two decades. Where can a beginner gain a reasonable introduction to the study of high temperature superconductors by STM? Below we list a select few of our favorite publications, with an eye towards the big picture and readability. Note that we don't necessarily agree with the conclusions drawn in these papers, but rather appreciate the quality of the presentation of information and find them to be very helpful as introductions to the material.

Two Gaps/Competing Order
Note that there is vast literature on this. These are just recent brief and more extended background and some recent experimental evidence for competing order (there is also evidence against -- we'll get around to mentioning some good ones in a bit)
