Growth mechanism and thermoelectric properties of PbTe/SnTe/PbTe heterostructures

Lattice-mismatched heteroepitaxy of IV-VI thin films on PbTe(001): Anab initiostudy

“…As exemplified in the PbTe/PbSe(001) quantum dot system [8], the residual strain in their interface regime causes a dislocation pattern along [110] and [110] directions, inducing formation of quantum dots. Complementing this, a recent experimental study [9] on the effect of compressive strain on SnTe-supported PbTe thin films also demonstrated that dislocation patterns will begin to appear when the thin film thickness exceeds 20Å, which roughly corresponds to six to seven monolayers of PbTe. For those quantum dots systems, fine control of the size and distribution of the unit cell is one of the key elements to achieve next generation quantum devices.…”

Solid state phase equilibria in the Te-rich region of the RE (RE=Ce, Nd and Pr)–Sn–Te ternary systems

“…The IV-VI compounds are promising candidate materials that can be utilized in thermoelectric, optoelectronic and the other applications [1][2][3][4]. Among them, the binary amorphous and crystalline SnTe and GeTe compounds have attracted numerous studies in the past decades [2,[5][6][7].…”

Thermoelectric Power in Quantum Dots Under Large Magnetic Field

“…They are also used in ultrasonic amplification [149]. It has been used not only as bulk but also as films [185][186][187][188], quantum wells [189], superlattices [190,191], nanowires [192], and colloidal and embedded nanocrystals [193][194][195][196]. In Sect.…”

“…PbTe, in particular, is the end compound of several ternary 1.2 Theoretical Background 7 and quaternary high-performance high-temperature thermoelectric materials [180][181][182][183][184]. It has been used not only as bulk but also as films [185][186][187][188], quantum wells [189], superlattices [190,191], nanowires [192], and colloidal and embedded nanocrystals [193][194][195][196]. PbTe films doped with various impurities have also been investigated [197][198][199][200].…”
