Simultaneous determination of the thermal diffusivity and a drum factor for CdBeMnTe crystals with the photoacoustic method

Photoacoustic spectroscopic investigations of optical and thermal properties of diluted magnetic CdBeMnTe crystals

“…The thermal diffusivity values of CdBeMnTe crystals computed from the ratio of the amplitudes of the PA signals of CdTe and CdBeMnTe crystals in the band to band absorption region agree very well with the values obtained from the frequency PA characteristics given in Table 1 and presented in paper [39].…”

Determination of Dissolved Iron Redox Species in Freshwater Sediment using DGT Technique Coupled to BDS

“…In contrast to the above enumerated methods, optothermal methods provide high-sensitivity measurements for spectroscopic characterization and detection of low-absorption transparent samples. [14][15][16][17] The high sensitivity of the optothermal methods has already been repeatedly improved by combining with other methods. [18][19][20][21][22] In this work the detection of iron species strongly bound in the resin gel was performed by the photothermal beam deflection spectroscopy (BDS).…”

On Investigations of the Optical Absorption Coefficient of Gold and Germanium Implanted Silicon with the Use of the Non-destructive Contactless Photo Thermal Infrared Radiometry

“…12 In this work we report results of investigations of Au 2+ and Ge + ion-implanted silicon with the Photo Thermal Infrared Radiometry (PTR) method. 13 This method is used for investigations of semiconductor materials like other photoacoustic (PA), [14][15][16][17][18][19][20] photopyroelectric [21][22][23] and Modulated Free Carriers Absorption (MFCA) [24][25][26][27][28] methods. The PTR method has a wide range of different applications in investigations of many types of materials.…”
