Scattering-dominated high-temperature phase of 1T-TiSe2: An optical conductivity study

László Forró, Helmuth Berger, Eduard Tutis, Neven Barisic

The controversy regarding the precise nature of the high-temperature phase of 1T-TiSe2 lasts for decades. It has intensified in recent times when new evidence for the excitonic origin of the low-temperature charge-density wave state started to unveil. Here ...

Pressure Induced Superconductivity in Pristine 1T-TiSe2

László Forró, Helmuth Berger, Eduard Tutis, Balazs Sipos

The interplay between superconductivity and the charge-density wave (CDW) state in pure 1T-TiSe2 is examined through a high-pressure study extending up to pressures of 10 GPa between sub-Kelvin and room temperatures. At a critical pressure of 2 GPa a super ...

From Mott state to superconductivity in 1T-TaS2

László Forró, Helmuth Berger, Ana Akrap, Eduard Tutis, Balazs Sipos

The search for the coexistence between superconductivity and other collective electronic states in many instances promoted the discovery of novel states of matter. The manner in which the different types of electronic order combine remains an ongoing puzzl ...

Investigation of the charge transport through disordered organic molecular heterojunctions

Libero Zuppiroli, Eduard Tutis, Hocine Houili

We present a three-dimensional multiparticle Monte Carlo (3DMPMC) simulation of hopping transport in disordered organic molecular media. We used this approach in order to study the charge transport across an energetically disordered organic molecular heter ...

Charge transport across organic-organic interfaces in organic light-emitting diodes

Libero Zuppiroli, Eduard Tutis, Hocine Houili

The process of hopping transport across organic heterojunctions is critical to the function of organic light-emitting diodes (OLED) and many other currently developed organic electronic devices. We consider the case of a hole-only or homopolar heterojuncti ...

Doping-induced charge trapping in organic light-emitting devices

Frank Nüesch, Libero Zuppiroli, Detlef Berner, Eduard Tutis, Xiao Wang

By using pyran-containing donor-acceptor dyes as doping molecules in organic light-emitting devices (OLEDs), we scrutinize the effects of charge trapping and polarization induced by the guest molecules in the electro-active host material. Laser dyes 4-(dic ...
