Midas: Our Workhorse Evaporator System
Midas is our workhorse evaporator system, dedicated to the preparation of Au/mica surfaces. Our work requires the use of many Au substrates in each series of experiments, and we have found that evaporated Au/mica films provide a practical alternative to single-crystals. In addition, the lateral dimensions can be arbitrarily large, thus facilitating infrared studies of weakly absorbing species.
