Simultaneous measurement of surface pontetial and transport response of graphene Hall bars
 Štrba, Lukáš ; Čech, Vladimír (referee) ; Bartošík, Miroslav (advisor)
Graphene is a semimetal with zero band gap. Position of Fermi level can be changed by applied gate voltage, which results in a change of free carier concentration. This work focuses on a simultaneous measurement of surface potential by Kelvin probe force microscopy (KPFM) and transport response of graphene Hall bars in different relative humidities and with applying gate voltage. The transport response was also observed in case of graphene Hall bar structure modified by local anodic oxidation (LAO).

Graphene sensor of relative humidity and gate-voltage influence
 Štrba, Lukáš ; Konečný, Martin (referee) ; Bartošík, Miroslav (advisor)
This work is focused on the observation of relative humidity and gate voltage effect on transport properties of graphene sensors in atmospheric conditions and in vacuum.
