Welcome to Hakki's Research Group for Low-Dimensional Material Growth!

Topic 1. Rock-salt structured materials

-Chloride: NaCl, KCl, AgCl etc

-Oxide: MgO, CaO, SrO, BaO etc

-Nitride: TiN, CrN, SmN etc

Topic 2. Water soluble ceramic materials

-Several chlorides and oxides which has solubility in water

(especially strong selectivity on water compare to other solvents)

-Growth mechanism of water soluble ceramic films and nano-structures

-Application to flexible function devices (display, energy, and organic devices) which need high-temperature processes

Topic 3. 2-Dimensional materials

-Growth of # of layer controlled high quality graphene sheet for gas dynamics and bio-molecule imaging.

-Study of phase transition mechanism of MoS2.

-Several 2D material growth (BN, Transition metal Di-chalcogenides (TMDCs), Silicene, etc).

Topic 4. 1 and 0-Dimensional materials

-Polarity induced nanostructure formation: nano facet (MgO), nanorods & wires (MgO, ZnO, etc).

-Transition or rare-earth metal oxide nanorod & wires (VO2, RuO2, TiO2, MoO2, WO2, and ReO3).

-Carbon nanotube growth.

-C60 synthesis and stacking of it.

-Nobel metal nanoparticles (Au, Pt, Ag, Pd etc) for plasmonic and catalytic applications.

Topic 5. Application of topic 1 ~ topic 4 materials to energy & light emitting device

-Solar cells (perovskite solar cells, organic solar cells, etc).

-Energy harvesting devices (Piezotronics, triboelectric, etc).

-Anode for Li battery.

-Light emitting diode (GaN based inorganic LEDs, organic LEDs).
