In 1984, we invented Si drift detectors that were initially deployed in the mid-1990s to provide accurate particle position reconstruction using a limited number of channels for nuclear physics experiments at CERN and Brookhaven’s Relativistic Heavy Ion Collider. Today, these detectors are a mainstay in x-ray spectroscopy for materials science. Our invention opened a new paradigm for charge transport in silicon and established silicon as the material of choice for room-temperature x-ray spectroscopy.
