• "Electronic Phase Diagram of Single-Element Silicon "Strain'' Superlattices"

Liu Z, Wu J, Duan WH, et al., Physical Review Letters 105 (1): 168-172 Jul 2010.  The evidence that the band gap of Si changes significantly with strain suggests that by alternating regions of strained and unstrained Si one creates a single-element electronic heterojunction superlattice (SL), with the carrier confinement defined by strain rather than by the chemical differences in conventional compositional SLs.

• "Observed Atmospheric Responses to Global SST Variability Modes: A Unified Assessment Using GEFA"

Wen N, Liu ZY, Liu QY, Frankignoul C, Journal of Climate 23(7): 1739-1759 Apr 2010.  This pilot study serves as a demonstration of the potential utility or GEFA in identifying multiple surface feedbacks to the atmosphere in the observation. 

• "Different genetic mechanisms control foliar and tuber resistance to phytophthora infestans in wild potato solanum verrucosum"

Liu ZY, Halterman D, American Journal of Potato Research 86 (6): 476-480 Nov 2009. Late blight, caused by the oomycete pathogen, Phytophthora infestans, is a devastating disease of potatoes and tomatoes. A key long-term management strategy for combating this disease is to develop potato cultivars with broad-spectrum and durable resistance through identification and integration of major resistance genes. In

• "Biomodality in a monostable climate-ecosystem: the role of climate variability and soil moisture memory"

Liu ZY, Journal of Climate 23 (6): 1447-1455 Mar 2010. The probabilistic modal response of vegetation to stochastic precipitation variability is studied in a conceptual climate-ecosystem model.
