Liquid Ge2Sb2Te5 studied by extended x-ray absorption
نویسندگان
چکیده
We report on x-ray absorption studies of the structure of the liquid phase of a prototypical phase-change material Ge2Sb2Te5 . We demonstrate that the local structure of liquid Ge2Sb2Te5 is very similar to that of amorphous Ge2Sb2Te5 . Ge atoms in the liquid phase are found to be covalently bonded suggesting a semiconducting nature of the melt.

Surface relaxation in liquid water and methanol studied by x-ray absorption spectroscopy
X-ray absorption spectroscopy is a powerful probe of local electronic structure in disordered media. By employing extended x-ray absorption fine structure spectroscopy of liquid microjets, the intermolecular O–O distance has been observed to undergo a 5.9% expansion at the liquid water interface, in contrast to liquid methanol for which there is a 4.6% surface contraction. Despite the similar p...
متن کاملStress Limited Scaling of Ge2Sb2Te5
The influence of stress on the phase change behaviour of Ge2Sb2Te5 encapsulated by ZnSSiO2 and TiN is investigated using temperature dependent Extended X-ray Asbsorption Fines Structure and Ellipsometry to determine the crystallisation temperature. The encapsulation material surrounding the Ge2Sb2Te5 has an increasingly dominant effect on the material’s ability to change phase and can cause a p...

Introduction: The effects of X-rays on carcinogens have been proven in recent years. Today, lead is used in many devices such as lead covers, thyroid protectors to protect the body against x-rays. But this equipment contains many disadvantages such as, Toxicity, High weight and Lack of flexibility. Today, newer methods, such as semi-solid skin care products (cream, ointment), a...
متن کاملBonding in liquid carbon studied by time-resolved x-ray absorption spectroscopy.
Even the most basic properties of liquid carbon have long been debated due to the challenge of studying the material at the required high temperature and pressure. Liquid carbon is volatile and thus inherently transient in an unconstrained environment. In this paper we use a new technique of picosecond time-resolved x-ray absorption spectroscopy to study the bonding of liquid carbon at densitie...
