[institut] [phys4phys] Reminder: Center for Solid State Physics and New Materials seminar: Aleksandar Matkovic, 20. 2. 2025. 12h

[Jelena Pesic]

Dear colleagues,

You are kindly invited to the Center for Solid State Physics and New 
Materials seminar, which will be held on Thursday, 20. 02. 2025., at 
12:00, in the library reading room "Dr. Dragan Popović" of the Institute 
of Physics Belgrade.

The talk, entitled "Phyllosilicates as functional dielectrics in two 
dimensional materials-based electronics" will be given by  Dr. 
Aleksandar Matkovic, Montanuniversität Leoben, Austria


Abstract:
Since the last decade, the number of isolated two-dimensional (2D) 
materials keeps growing exponentially, focusing on high-performance 
semiconducting and spontaneously polarized materials. However, the 
number of vdW insulators is extremely disproportional to both 
semiconductors and metals. Almost exclusively the entire field relies on 
hexagonal boron nitride. Surely, this cannot be the only technologically 
relevant system.

Inspired by naturally occurring van der Waals (vdW) crystals – 2D 
minerals – from the phyllosilicate family, our team works on 
establishing 2D phyllosilicates as a vdW dielectric platform. In this 
talk, we will focus first on the potential application of non magnetic 
phyllosilicates – hBN alternatives – in 2D materials-based transistors, 
and opportunities for this material class to be used as charge-trap 
layers for computing in memory applications. Afterwards, we will look 
into intrinsic magnetism in phyllosilicates, magnetic domains, their 
layered antiferromagnetic ordering, and ion implementation as a 
potential pathway to engineer magnetic impurities.



Best regards,
Jelena Pesic
