“…Bi 2 Se 3 ordinarily forms n-type specimens, so that more literature on n-type is available. Typical n-type mobilities at or even somewhat above these concentrations [35][36][37][38][39][40][41] are in this range or higher, so that assuming no great asymmetry in n-type vs p-type scattering rates, the assumed p-type mobilities are reasonable. The assumed carrier concentration dependence implies that mobility increases significantly as carrier concentration decreases, which is generally true until one reaches a limiting value, as in Ref.…”

We present an analysis of the potential thermoelectric performance of hole-doped Bi 2 Se 3 , which is commonly considered to show inferior room temperature performance when compared to (2008).]) the material may show optimized ZT values of unity or more in the 300-500 K temperature range and thus be suitable for cooling and moderate temperature waste heat recovery and thermoelectric solar cell applications. Central to this conclusion are the larger band gap and the relatively heavier valence bands of Bi 2 Se 3 .

“…To date, all ARPES measurements on Bi 2 Q 3 (Q=Se, Te) were done on cleaved single crystal surfaces, while for transport measurements or device applications, thin films are desired. In the literature, many works have already been done in the preparation of Bi 2 Q 3 thin films by various techniques, such as electrodeposition [11,12], chemical bath deposition (CBD) [13], solvo thermalization [14], successive ionic layer adsorption and reaction (SILAR) [15], thermal evaporation [16], reactive evaporation [17], metal-organic chemical vapor deposition [18] and compound evaporation [19,20], etc. However, these methods normally produce polycrystalline films aiming for thermoelectric applications, which are far from meeting the present requirements.…”

“…The effective cooling is proportional to the number of n-p materials used in the module. Geometric dimensions and the number of the thermocouples have significant influence on thermoelectric performance and the mechanical reliability The preferred materials for these devices are bismuth selenide (Bi 2 Se 3 ) [10], bismuth telluride (Bi 2 Te 3 ) and antimony telluride (Sb 2 Te 3 ) [11], for their stable performance from 180 to 400 K.…”

Thermoelectrics, in particular solid-state conversion of heat to electricity and vice versa, is expected to be a key energy harvesting and temperature management solution in coming years. There has been a resurgence in the search for new materials for advanced thermoelectric energy conversion applications and to enhance the properties of existing materials. In this paper, we review recent efforts on improving figure-of-merit (ZT) through alloying and nano structuring. As heatsink characteristics dictate the performance of thermoelectric modules, various types of heatsink designs has been investigated. Several reported strategies for improving ZT are critically assessed. A notable increase in figure-of-merit of thermoelectric materials (TE) has opened up new areas of applications especially in the medical field. Peltier cooling devices are widely employed for patient core temperature control, skin cooling, medical device and laboratory equipment cooling. Application of these devices in the medical field both in temperature control and power generation has been studied in detail. It is envisioned that this study will provide profound knowledge on the thermoelectric based materials and its role in medical applications.
