Exploring High-Temperature Superconductivity and the Pseudogap

Using both scanning tunneling microscopy (STM) and angle-resolved photo-electron spectroscopy (ARPES) gives researchers a more complete understanding of high-temperature superconducting materials. STM can show actual atoms on the material's surface. ARPES uses the photoelectric effect by aiming a beam of light (photons) at the material's surface. The photons excite atoms in the material, causing them to eject electrons, which are then captured by a detector. The momentum (speed and direction) of the ejected electrons give researchers information about the momentum of electrons inside the material.

Sarychev Peak : Location: 48.1N, 153.2E
Elevation: 4906 feet (1496 m)
Sarychev Peak, a stratovolcano, is the most active volcanoes in the Kurile Islands. Sarychev Peak erupted at least 14 times between 1765 and 1989. The largest eruption (VEI=4) was in 1924. Most eruptions are moderate to moderate-large (VEI=2-3) and explosive. An eruption in 1960, the last major eruption, produced a 3 mile (5 km) high ash cloud. An eruption in 1964 lasted only 6 minutes.
