## Description

DTU intents to purchase a Laser CO2 heater with substrate surfaces with a specific atomic termination and reconstruction are essential for controlled epitaxial growth. The reason for this is that is  that Laser heating (typically CO2 lasers in ultrahigh vacuum) is a proven in situ method to produce atomically flat, single-terminated oxide surfaces (e.g., SrTiO3, LaAlO3, sapphire) by rapid high-temperature annealing and quenching. For DTU, this capability offers clear advantages: a one-step, high-throughput preparation that simultaneously produces atomically smooth, evenly spaced terraces and the desired surface reconstruction; in situ processing that preserves structural quality and chemical purity; and spatially selective treatment that minimizes damage to surrounding areas. These factors make laser heating an efficient, reliable investment for reproducible, high-quality substrate preparation needed for advanced epitaxial research and device fabrication.
