Passivating contacts for homojunction solar cells using a-Si:H/c-Si hetero-interfaces

Bénédicte Demaurex

Crystalline silicon (c-Si) homojunction solar cells account for over 90% of the current photovoltaic market. However, further progress of this technology is limited by recombinative losses occurring at their metal-semiconductor contacts. The goal of this t ...

Electron and Hole Mobilities in Single-Layer WSe2

Andras Kis, Adrien Victor Allain

Single-layer transition metal dichalcogenide WSe2 has recently attracted a lot of attention because it is a 2D semiconductor with a direct band gap. Due to low doping levels, it is intrinsic and shows ambipolar transport. This opens up the possibility to r ...

Single-layer MoS₂ : Electronics in Two Dimensions

Branimir Radisavljevic

This thesis explores the electronic properties of one layered transition-metal dichalcogenide – single-layer MoS2, and demonstrates the first transistors and integrated circuits with characteristics that outperform graphene electronics in many aspects and ...

Impact Ionization and Carrier Multiplication in Graphene

Yusuf Leblebici, Luca Pirro

We develop a model for carrier generation by impact ionization in graphene, which shows that this effect is non-negligible because of the vanishing energy gap, even for carrier transport in moderate electric fields. Our theory is applied to graphene field ...

Linear and Time-Resolved THz Spectroscopy of Photonic and Charge Transporting Systems

Jan Cornelius Brauer

Photo-induced charge separation and charge transport are fundamental processes in many energy conversion techniques, where light is converted into chemical energy (PEC), into electrical energy (solar cells) or in the opposite sense if electrical energy is ...

Field-Effect Transistors Based on ZnO Nanowires

Daniel Dominik Kälblein

Semiconductor nanowires are an emerging class of materials with great potential for applications in future electronic devices. The small footprint and the large charge-carrier mobilities of nanowires make them potentially useful for applications with high- ...

Polarization Screening in Multiferroic (Ga,Mn)As/P(VDF-TrFE) Transistors

Nava Setter, Igor Stolichnov, Evgeny Mikheev, Sebastian Riester

Ferroelectric copolymers of polyvinylidene fluoride and trifluoroethylene are attractive gate materials because of a rather high remanent polarization, low dielectric permittivity, and easy integration on semiconductors due to the low processing temperatur ...

Modeling methodology of high-voltage substrate minority and majority carrier injections

Maher Kayal, Jean-Michel Sallese, Fabrizio Lo Conte

This paper presents a modeling methodology for substrate current coupling mechanisms. An enhanced model of the diode ensuring continuity of minority carriers is used to build an equivalent schematic, accounting for minority and majority carrier propagation ...

A circuit-level substrate current model for smart-power ICs

Maher Kayal, François Krummenacher, Jean-Michel Sallese, Marc Pastre, Fabrizio Lo Conte

This paper presents a new modeling methodology accounting for generation and propagation of minority carriers that can be used directly in circuit-level simulators in order to estimate coupled parasitic currents. The method is based on a new compact model ...

The Effect of Interface Modification on the Properties of Organic Thin-Film Transistors

Franziska Dora Fleischli

In organic thin-film transistors (OTFTs), the conducting channel is located near the interface between the organic semiconductor and the dielectric; this interface is crucial for transistor performance. The goal of this thesis is to study the effect of thi ...
