Electric-field-, temperature-, and stress-induced phase transitions in relaxor ferroelectric single crystals

Nava Setter, Dragan Damjanovic, Matthew Davis

Electric-field-induced phase transitions have been evidenced by macroscopic strain measurements at temperatures between 25 degrees C and 100 degrees C in 001-poled (1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) [(PMN-xPT);x=0.25,0.305,0.31] and (1-x)Pb(Zn1/3Nb2/3)O ...

Electromechanical properties and self-polarization in relaxor Pb(Mg1/3Nb2/3)O-3 thin films

Nava Setter, Dragan Damjanovic, Zian Kighelman

Pyrochlore free Pb(Mg1/3Nb2/3)O-3 (PMN) thin films were prepared from alkoxide-based solution precursors. The influence of different seeding layers and chemical solution on the microstructures is shown. Dielectric, electrostrictive, and piezoelectric prope ...

High resolution study of domain nucleation and growth during polarization switching in Pb(Zr,Ti)O-3 ferroelectric thin film capacitors

Nava Setter, Paul Muralt, Alexander Tagantsev, Enrico Colla

The domain nucleation and growth during polarization switching in Pb(Zr,Ti)O-3 (PZT) ferroelectric thin film capacitors with Pt top (TE) and bottom electrodes (BE) were studied by means of atomic force microscopy (AFM). The experimental configuration used ...

Observation of domain nucleation and growth during switching process

Nava Setter, Paul Muralt, Alexander Tagantsev, Enrico Colla

The domain nucleation and growth during the switching process in ferroelectric PZT thin film capacitors was observed using atomic force microscope (AFM) technique combined with a lock-in amplifier. The measured phase difference between the tip vibration si ...

Quantum confined Stark effect due to built-in internal polarization fields in (Al,Ga)N/GaN quantum wells

Nicolas Grandjean

(Al,Ga)N/GaN quantum wells have been studied by temperature-dependent luminescence and reflectivity. The samples were grown by molecular beam epitaxy on (0001) sapphire substrates, and well widths were varied from 3 to 15 monolayers (ML's) with a 2-ML incr ...

Transient photocurrents in lead zirconate titanate thin films

Nava Setter

Transient photocurrents are investigated in ferroelectric lead zirconate titanate (PZT) films illuminated by laser pulses in the spectral range of 340-380 nm. At low electric fields, the photocurrent is sensitive to the ferroelectric polarization state and ...

Interferometric measurements of electric field-induced displacements in piezoelectric thin films

Nava Setter

Interferometric measurements of electric field-induced displacements in piezoelectric thin films using single-beam and double-beam optical detection schemes are reported. It is shown that vibrational response measured with a single-beam interferometer incl ...
