Transverse laser induced thermoelectric voltage effect in tilted La0.5Sr0.5CoO3 thin films

“…The laser induced thermoelectric voltage (LITV) effect was firstly found in normal state YBa 2 Cu 3 O 7-d thin films [1][2][3][4], which initiated a large number of investigations on this effect as it has great potential application in photoelectric detectors, thermoelectric detectors and for conversion of waste heat to electricity. Untill now, this effect in Bi 2 Sr 2 CaCu 2 O 8 [5], La 1 À x Ca x MnO 3 [6][7][8], La 1 À x Pb x MnO 3 [9], La 2 À x Sr x CuO 4 [10], Ca x CoO 2 [11][12][13] and Bi 2 Sr 2 Co 2 O y [14] thin films has been investigated when films are tilted.…”

Light-induced off-diagonal thermoelectric effect via indirect optical heating of incline-oriented CaxCoO2 thin film

“…[1][2][3][4][5]12,13 These voltage signals showed very fast evolution and decay time of several 10 ns, which suggested that the incline-oriented films can be potential candidates for thermal-type optical detectors with high-speed. Also, the "V x 6 k DT z " feature allows us to independently modify the electric and thermal design of the films, which makes this phenomenon more attractive for device development.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Pioneering studies on YBa 2 Cu 3 O 7-d thin films have revealed that this phenomenon emerges uniquely in anisotropic materials when they are fabricated in an inclined crystallographic orientation. [1][2][3][4][5] Figure 1(a) shows an example of the crystallographic orientation necessary to develop the ODTE effect. The material shown here is a layered cobaltite Ca x CoO 2 , which exhibits highly anisotropic properties between the ab plane and the c axis.…”

Far infrared video detection and difference frequency mixing with tilted c-axis epitaxial YBa2Cu3O7−δ thin films

“…The coherent growth of such films on appropriately oriented substrates has been established by the observation of a tilt angle dependent lateral thermoelectric effect in the normal state. 7 These films, available as fast optical radiation detectors ͑ForTech HTS, Regensburg, Germany͒, have a response extending from UV to FIR wavelengths.…”
