Si(111) -7x7 at 600C dynamic impurity or carbonating processes can be observed

Product Description:

With the STM Aarhus 150 HT, SPECS introduces a unique high temperature version by advanced heat flow management to allow imaging metals and semiconductors at elevated temperatures above 1000C. While standard STMs at high temperatures normally operate with direct current heating only, the STM Aarhus 150 HT operates with radiative heating to allow sample systems being used that are completely independent e.g. from semiconductor doping levels. The advanced heat flow management allows imaging at elevated temperatures without measurement time limitations. Even at temperatures exceeding 1000C all temperatures reach equilibrium within minutes to allow constant imaging with ultimate low drift for as long as desired by the experimentalist.
